MELAMINE

EC / List no.: 203-615-4
CAS no.: 108-78-1
Mol. formula: C3H6N6

Melamine /ˈmɛləmiːn/ is an organic compound with the formula C3H6N6.
This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton.
Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred.
Melamine can be combined with formaldehyde and other agents to produce melamine resins.
Such resins are characteristically durable thermosetting plastic used in high pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards.
Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.

Melamine is sometimes illegally added to food products in order to increase the apparent protein content.
Ingestion of melamine may lead to reproductive damage, or bladder or kidney stones, and bladder cancer.
It is also an irritant when inhaled or in contact with the skin or eyes.
The United Nations' food standards body, the Codex Alimentarius Commission, has set the maximum amount of melamine allowed in powdered infant formula to 1 mg/kg and the amount of the chemical allowed in other foods and animal feed to 2.5 mg/kg.
While not legally binding, the levels allow countries to ban importation of products with excessive levels of melamine.

Etymology
The German word Melamin was coined by combining the words Melam (a derivative of ammonium thiocyanate) and amine.
Melamine is, therefore, unrelated etymologically to the root melas (μελας, meaning "black" in Greek), from which the words melanin, a pigment, and melatonin, a hormone, are formed.

Uses
In one large-scale application, melamine is combined with formaldehyde and other agents to produce melamine resins.
Such resins are characteristically durable thermosetting plastic used in high-pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards.

Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.

Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.

Melamine also enters the fabrication of melamine polysulfonate, used as a superplasticizer for making high-resistance concrete.
Sulfonated melamine formaldehyde (SMF) is a polymer used as a cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during handling and pouring.
It results in concrete with a lower porosity and a higher mechanical strength, exhibiting an improved resistance to aggressive environments and a longer lifetime.

The use of melamine as fertilizer for crops had been envisioned during the 1950s and 1960s because of its high nitrogen content (2/3).
However, melamine is much more expensive to produce than are other common nitrogen fertilizers, such as urea.
The mineralization (degradation to ammonia) for melamine is slow, making this product both economically and scientifically impractical for use as a fertilizer.

Melamine and its salts are used as fire-retardant additives in paints, plastics, and paper.
A melamine fibre, Basofil, has low thermal conductivity, excellent flame resistance and is self-extinguishing; this makes it useful for flame-resistant protective clothing, either alone or as a blend with other fibres.

Melamine derivatives of arsenical drugs are potentially important in the treatment of African trypanosomiasis.

Melamine use as non-protein nitrogen (NPN) for cattle was described in a 1958 patent.
In 1978, however, a study concluded that melamine "may not be an acceptable non-protein N source for ruminants" because its hydrolysis in cattle is slower and less complete than other nitrogen sources such as cottonseed meal and urea.

Melamine is sometimes illegally added to food products in order to increase the apparent protein content.
Standard tests, such as the Kjeldahl and Dumas tests, estimate protein levels by measuring the nitrogen content, so they can be misled by adding nitrogen-rich compounds such as melamine.
There are instruments available today which can differentiate melamine nitrogen from protein nitrogen.

Regulation in food and feed
The United Nations' food standards body, Codex Alimentarius Commission, has set the maximum amount of melamine allowed in powdered infant formula to 1 mg/kg and the amount of the chemical allowed in other foods and animal feed to 2.5 mg/kg.
While not legally binding, the levels allow countries to ban importation of products with excessive levels of melamine.

Synthesis and reactions
Melamine was first synthesized by the German chemist Justus von Liebig in 1834. In early production, first calcium cyanamide was converted into dicyandiamide, which was heated above its melting temperature to produce melamine. Today most industrial manufacturers use urea in the following reaction to produce melamine:

6 (NH2)2CO → C3H6N6 + 6 NH3 + 3 CO2
In the first step, urea decomposes into cyanic acid and ammonia:

(NH2)2CO → HNCO + NH3
Cyanic acid polymerizes to cyanuric acid, which condenses with the liberated ammonia forming melamine.
The released water reacts with cyanic acid, which helps to drive the reaction:

6 HNCO + 3 NH3 → C3H6N6 + 3 CO2 + 3NH3
The above reaction can be carried out by either of two methods: catalyzed gas-phase production or high pressure liquid-phase production.
In one method, molten urea is introduced onto a fluidized bed with catalyst for reaction. Hot ammonia gas is also present to fluidize the bed and inhibit deammonization.
The effluent then is cooled. Ammonia and carbon dioxide in the off-gas are separated from the melamine-containing slurry.
The slurry is further concentrated and crystallized to yield melamine.
Major manufacturers and licensors such as Orascom Construction Industries, BASF, and Eurotecnica have developed some proprietary methods.

The off-gas contains large amounts of ammonia.
Therefore, melamine production is often integrated into urea production, which uses ammonia as feedstock.

Crystallization and washing of melamine generates a considerable amount of waste water, which may be concentrated into a solid (1.5–5% of the weight) for easier disposal.
The solid may contain approximately 70% melamine, 23% oxytriazines (ammeline, ammelide, and cyanuric acid), 0.7% polycondensates (melem, melam, and melon).
In the Eurotecnica process, however, there is no solid waste and the contaminants are decomposed to ammonia and carbon dioxide and sent as off gas to the upstream urea plant; accordingly, the waste water can be recycled to the melamine plant itself or used as clean cooling water make-up.

Melamine reacts with acid and related compounds to form melamine cyanurate and related crystal structures, which have been implicated as contaminants or biomarkers in Chinese protein adulterations.

Drug derivatives
Melamine is part of the core structure for a number of drugs including almitrine, altretamine, cyromazine, ethylhexyl triazone, iscotrizinol, meladrazine, melarsomine, melarsoprol, tretamine, trinitrotriazine, and others.

Methods of Manufacturing
Melamine is produced from urea by a high or low pressure process in either one or two stages.
In the low pressure route, the reaction is carried out in the vapour phase generally using an alumina catalyst.
Urea forms isocyanic acid, which is converted first to cyanamide and then to melamine.
In the high pressure process, carried out in the liquid phase without a catalyst, urea forms cyanuric acid which is reacted with ammonia to form melamine.
Carbon dioxide and ammonia by-products are recycled to urea.

It is used in the manufacture of melamine resins, laminates, surface coating resins, plastic molding compounds, textile resins, bonding resins, gypsum melamine resin mixtures, orthopedic casts, rubber additives and paper products.

Melamine is a nitrogen-based compound used by many manufacturers to create a number of products, especially plastic dishware. It’s also used in:

utensils
countertops
plastic products
dry-erase boards
paper products
While melamine is widely found in many items, some people have raised safety concerns that the compound could be toxic.

Is Melamine safe?
The short answer is yes, Melamine is safe.

When manufacturers create plasticware with melamine, they use high heat to mold the substances.

While the heat uses up most of the melamine compounds, a small amount does usually remain in the plates, cup, utensils or more.
If melamine gets too hot, it can start to melt and potentially leak into food and drink products.

What is Melamine?

Melamine is a chemical compound with a number of uses, including manufacturing laminates, glues, dinnerware, and more.
This hard plastic can also be made in a wide range of colors and styles, making it an extremely versatile product that can be used in a variety of settings.
It is created by combining melamine resin with strengthening materials, which means it can stand up to the rigors of everyday use.

Is Melamine Tolerant to Hot and Cold Uses?
Melamine is an insulator, not a conductor.
This means that while it may maintain temperatures longer than other types of plastic, it takes a long time for the temperature of the material to change.
So, melamine stays cool to the touch when serving hot foods because the food does not produce enough heat for a long enough period of time to change the temperature of the material itself.
This protects restaurant servers and diners from burn hazards associated with hot plates and other servingware.
Thanks to its heat-resistant properties, melamine is also great for kitchen tools that are used when handling hot soups and boiling water.

Because melamine is such a great insulator, it's also ideal for cold food and buffet displays.
Melamine food pans are great for cold applications like deli displays, buffets, salad bars, and more.
For a stylish catered display, place melamine in an ice-filled container to keep plated items cool.

Where is Melamine Used?
Thanks to its durable, light weight construction, melamine is a popular choice for a variety of commercial settings, like dining halls, day care facilities, and assisted living communities.
However, you can find designer melamine dinnerware that looks just like handcrafted ceramic for an upscale feel that's appropriate in more sophisticated restaurants.
The low risk of breakage makes melamine an ideal choice for restaurants that serve appetizers poolside or on the beach.
From bistros to barbecue shacks, you can find melamine dinnerware that suits the decor of nearly any foodservice establishment.
Melamine's durability makes it ideal for use in a variety of outdoor or high-volume settings.

What is melamine?

Melamine is a chemical that has many industrial uses.
In the United States, it is approved for use in the manufacturing of some cooking utensils, plates, plastic products, paper, paperboard, and industrial coatings, among other things.
In addition, although it is not registered as a fertilizer in the U.S., melamine has been used as a fertilizer in some parts of the world.

Melamine may be used in the manufacturing of packaging for food products, but is not FDA-approved for direct addition to human food or animal feeds marketed in the U.S.

What Even Is Melamine?
Melamine is chemical compound originally found to be toxic only in large quantities and in those cases, results in negative effects on kidney function.
However, new research is shedding light on just how much damage can be done to the human body from ingesting melamine.
Exposure to melamine has negative impacts on brain development and reproductive functions because it changes how hormones work in the body.

Where is Melamine Found?
Melamine can be found in pretty much every type of dishware, cups, plates, bowls and utensils as the compound makes these things dishwasher safe, inexpensive to produce, and extremely durable.
Remember how I mentioned before that these plates don't look like they're plastic?

melamine, also called cyanuramide or triaminotriazine, a colourless crystalline substance belonging to the family of heterocyclic organic compounds, which are used principally as a starting material for the manufacture of synthetic resins.
Melamine is rich in nitrogen, a property that is similar to protein.

Manufacture and applications of melamine
Melamine can be manufactured from dicyandiamide, hydrogen cyanide, or urea. Modern commercial production of melamine typically employs urea as a starting material.
Urea is broken down to cyanuric acid, which then can be reacted to form melamine.
Its most important reaction is that with formaldehyde, forming melamine-formaldehyde resins of high molecular weight.
These compounds form under the influence of heat and then become fixed into an insoluble and infusible mold; this process is known as thermosetting.
Melamine-based thermoset materials contain cross-linked polymers, which make the fixed molds strong and durable.
Usually formulated with fillers and pigments, melamine resins can be molded into dishes, containers, utensils, handles, and the like or used as laminating agents or coating materials for wood, paper, and textiles.
Formica and Melmac are well-known trade names for products based on melamine resins.

Melamine has also been incorporated into a variety of flame-retardant materials. This application is based on the compound’s high nitrogen content.
When exposed to heat, melamine degrades and releases nitrogen.
The freed nitrogen takes the place of oxygen in the surface air surrounding the material, which prevents the material from burning.
Butylated melamine resins, made by incorporating butyl alcohol into the melamine–formaldehyde reaction mixture, are fluids used as ingredients of paints and varnishes.
A copolymer containing melamine, formaldehyde, and sodium bisulfite produces a foam with sound-absorbing and flame-retardant properties.
The foam has a notably hard microbubble structure, which gives it an abrasive quality that has been utilized in the development of cleaning products
