The product is used in some eco-friendly bleaches and other cleaning products, and as a laboratory source of anhydrous hydrogen peroxide.

History of Sodium percarbonate:
Sodium percarbonate was first prepared in 1899 by Russian chemist Sebastian Moiseevich Tanatar.[2]

Structure of Sodium percarbonate:
At room temperature, solid sodium percarbonate has the orthorhombic crystal structure, with the Cmca crystallographic space group. The structure changes to Pbca as the crystals are cooled below about −30 °C.[3]

Chemistry
Dissolved in water, sodium percarbonate yields a mixture of hydrogen peroxide (which eventually decomposes to water and oxygen), sodium cations Na+
, and carbonate CO2−

Production
Sodium percarbonate is produced industrially by crystallization of a solution of sodium carbonate and hydrogen peroxide, with proper control of the pH and concentrations.[5][3][6] This is also a convenient laboratory method.

Alternatively, dry sodium carbonate may be treated directly with concentrated hydrogen peroxide solution.[7]

World production capacity of this compound was estimated at several hundred thousand tons for 2004.[8]

Uses
As an oxidizing agent, sodium percarbonate is an ingredient in a number of home and laundry cleaning products, including non-chlorine bleach products such as Oxyper, OxiClean, Tide laundry detergent,[1] and Vanish.[4]

Many commercial products mix a percentage of sodium percarbonate with sodium carbonate. The average percentage of an "Oxy" product in the supermarket is 65% sodium percarbonate and 35% sodium carbonate. The "ultra boosters" seen on infomercials may contain as much as 80% sodium percarbonate. However, sodium percarbonate is less expensive in its pure form[citation needed] and can be adjusted to any percentage the user desires.

Sodium percarbonate is also used as a no-rinse cleaning agent in at-home breweries. [9]

Sodium percarbonate can be used in organic synthesis as a convenient source of anhydrous H2O2, in particular in solvents that cannot dissolve the carbonate but can leach the H2O2 out of it.[10] A method for generating trifluoroperacetic acid in situ for use in Baeyer–Villiger oxidations from sodium percarbonate and trifluoroacetic anhydride has been reported; it provides a convenient and cheap approach to this reagent without the need to obtain highly concentrated hydrogen peroxide

(Sodium carbonate peroxyhydrate) is a coated and stabilized sodium percarbonate that serves as a powerful oxygen bleaching agent for cleaning, whitening, stain removal, hygiene, disinfection, water softening and product compaction. Percarbonate comes in a powder form and is one of the most effective stain removers and disinfectants ౼ outperforming liquid alternatives ౼ especially when used in synergy with a bleach activator or catalyst.

It combines the dual properties of sodium carbonate and hydrogen peroxide to deliver significant benefits in the Homecare industry. Sodium percarbonate is mainly used in laundry powder, automatic dishwashing tablets or bleach and laundry additives but can also be used in other applications where a solid, easy to use source of alkaline hydrogen peroxide is needed. These situations include water treatment, soil remediation, fish and shrimp farming and textile bleaching for example.

Sodium percarbonate carbonate is insoluble, but other than that, H2O2 leaching solvents, especially anhydrous H2O2, can be used in organic synthesis as a suitable source. Coated sodium percarbonate particles, the process for their preparation, relates to their use in detergent compositions and detergent compositions containing them. Containing coated particles of sodium percarbonate:

a) a core of sodium percarbonate and
b) a coating representing 5 to 20% by weight of the coated sodium particle, a coating, a hydrate, formation of an inorganic salt comprising at least one coating layer containing at least 25%, a salt of at least 75% by weight, in the form of a hydrate is. The coated sodium percarbonate particles containing them are the process for their preparation, their use in detergent compositions and in detergent compositions.

The use of sodium percarbonate (or sodium carbonate peroxyhydrate) as an active bleach component in detergent compositions for household laundry or dishwashing is well known. Generally, these detergent compositions contain among the zeolites other ingredients such as builder, enzymes, bleach activators and / or perfumes. This is due to the release of active oxygen in sodium percarbonate bleaching that decomposes during washing. However, the interaction between sodium percarbonate and other formulation ingredients leads to the gradual premature decomposition of percarbonate and hence the loss of bleaching power of the composition during storage and shipping. Percarbonate is heated or stored in the presence of moisture, this progressive decomposition is accelerated. As a result, the product is marketed in southern countries, for example storage of sodium percarbonate in a humid and hot environment is difficult. One of the important properties of the coated sodium carbonate particles according to the invention is the control amount of sodium carbonate in monohydrate form. In this regard, special attention exists to bring the temperature control of the core particles of the solution used to coat them during painting and temperature control of the coated particles during the manufacture of the coated particles to induce a proper crystallization of sodium carbonate in the coating in monohydrate form. The exact temperature to produce the monohydrate form may vary, depending on the air flow, the relative humidity of the air, and the drying time of the particles in the drying bed, drying. However, under many standard conditions, core particles are generally dried at temperatures between 60 and 75 ° C, contacted with a coating solution at a temperature between 45 and 60 ° C and the coated particles. Consequently, at the same time the invention is contacted with uncoated sodium percarbonate core particles with a coating solution containing sodium carbonate and the coated particles at a temperature of between 45 and 60 ° C. A process for preparing the coated sodium percarbonate particles according to the invention is between 60 and 75 ° C. dried at temperature. Sodium percarbonate core particles are prepared by crystallization of sodium percarbonate from a mass saturated solution, e.g. obtainable percarbonate solution, sodium carbonate and hydrogen peroxide. In addition, aqueous solutions of hydrogen peroxide and an aqueous soda ash can be sprayed onto the seeds of sodium percarbonate in a fluidized bed or by reaction with solid sodium carbonate with an aqueous solution of hydrogen peroxide, for example, in a fluidized bed process. Preferably, so The dium percarbonate core particles are obtained by a crystallization process using a salt-extracting agent.

In the process according to the invention, it is recommended that the coating solution contains sodium carbonate, an excess of 23% by weight. The core particles can be contacted with the coating solution in a mixer. However, it is recommended that the core particles come into contact with the coating solution by spraying the coating solution on the core in a fluidized bed. In another recommended arrangement, the coating is carried out in two stages, a first and a second fluidized bed using a mixer. The coated sodium percarbonate particles according to the invention can advantageously be used as an active bleach component in detergent compositions. Therefore, the present invention also relates to the above-described coated sodium percarbonate particles as the active bleach component in detergent compositions to use. The present invention also relates to detergent compositions containing the active bleach component of zeolite or non-zeolite or coated sodium percarbonate particles described above and a builder. Detergent compositions may also contain other ingredients such as surfactants, antiredeposition and soil suspending agents, bleach activators, optical brightening agents, soil release agents, suds controlling agents, enzymes, fabric softening agents, perfumes, colors, and processing aids. Adding the coated percarbonate particles according to the invention, in the form of powder or granules of a detergent with a bulk density of 1.0 to 0.4 g / cm ^ and internal zeolite or phosphate detergent tablets, especially sodium percarbonate is advantageous.tes core. When the coating layer is in a hydrated state, its water acceptance capacity is expelled. These known coating layers simultaneously have the dissolution rate used in washing applications, which does not result in the optimum combination of properties that may impart good stability to the sodium percarbonate present in the detergent composition, when the detergent is stored in a fast, hot and humid environment.
