Ammonium Lignosulfonate is water soluble yellow brown powder,is mainly used agriculture as irrigation and spray fertilizer.
Ammonium Lignosulfonate is used for its properties as dust suppressant, anti-caking & dusting in fertilizer particles.
Ammonium Lignosulfonate is also used for stimulation of germination procedure.
Ammonium Lignosulfonate is an odorless chemical and is available in light tan to dark brown color with thickness similar to that of motor oil.
Ammonium Lignosulfonate is a kind of natural anionic surfactant of high molecular polymer, which is rich in sulfo group and carboxyl and has better surf activity, water- solubility and dispersion force.
Extensively used in food industry as a de-foaming agent for paper production, Ammonium Lignosulfonate has antimicrobial and preservative properties.
Owing to purity and precise ph value, Ammonium Lignosulfonate is also used for construction, ceramics and mineral powder.
Ammonium lignosulphonate is mainly used as soluble fertilizer for drip irrigation or forliar spray,Also used for animal feed additives,dust suppresant,binder and so on.
Lignosulfonates have a wide variety of applications.
The single largest use for lignosulfonates is as plasticizers in making concrete,[1] where they allow concrete to be made with less water (giving stronger concrete) while maintaining the ability of the concrete to flow. Lignosulfonates are also used during the production of cement, where they act as grinding aids in the cement mill and as a rawmix slurry deflocculant (that reduces the viscosity of the slurry).
Lignosulfonates are also used for the production of plasterboard to reduce the amount of water required to make the stucco flow and form the layer between two sheets of paper. The reduction in water content allows lower kiln temperatures to dry the plasterboard, saving energy.
The ability of lignosulfonates to reduce the viscosity of mineral slurries is used to advantage in oil drilling mud, where it replaced tannic acids from quebracho (a tropical tree).
Lignosulfonates are used to disperse pesticides, dyes, carbon black, and other insoluble solids and liquids into water. They are used in tanning leather. They are also used to suppress dust on unpaved roads.
Oxidation of lignosulfonates from softwood trees produced vanillin (artificial vanilla flavor).
Dimethyl sulfide and dimethyl sulfoxide (an important organic solvent) are produced from lignosulfonates. The first step involves heating lignosulfonates with sulfides or elemental sulfur to produce dimethyl sulfide. The methyl groups come from methyl ethers present in the lignin. Oxidation of dimethyl sulfide with nitrogen dioxide produces dimethyl sulfoxide (DMSO). [1]
Also one of the very wide uses of lignosulfonates is deflocculation of clays used in drilling fluids in the oil and gas industry. Furthermore, lignosulphates are being researched for use in enhanced oil recovery (EOR) due to their ability to reduce IFT in foams, allowing for improved sweep efficiency, and hence increased recovery factor.
Aqueous lignosulfonate solutions are also widely used as a non-toxic dust suppression agent for unpaved road surfaces, where it is popularly, if erroneously, called "tree sap". Roads treated with lignosulfonates can be distinguished from those treated with calcium chloride by color: lignosulfonates give the road surface a dark grey color, while calcium chloride lend the road surface a distinctive tan or brown color. As lignosulfonates do not rely on water to provide their binding properties, they tend to be more useful in arid locations.
They also form a constituent of the paste used to coat the lead-antimony-calcium or lead-antimony-selenium grids in a Lead-acid battery.
Besides their use as dispersants lignosulfonates are also good binders. They are used as binders in well-paper, particle boards, linoleum flooring, coal briquettes, and roads.
The anti-oxidant effect of lignosulfonates is utilized in feeds, ensilage and flame retardants.
The UV absorbance of lignosulfonates is utilized in sun screens and bio-pesticides.

Application
1.Use as fertilizer in agriculture.
Builds a stronger root system by increasing root respiration and root formation.
Increases the Cation Exchange Capacity of the soil and facilitates nutrient absorption.
Great source of energy for beneficial soil organisms, which influence both soil fertility and plant health.
Improves aeration of soil and water retention in heavy and compact soils.
Prevents water and nutrient losses in light sandy soils.
Healthier roots hold soil, minimizing erosions
When added directly to soil it improves its quality and ability to grow crops
When added to urea, fertiliser and lime it improves their performance
When added to seeds it improves their strike rate and encourages root growth
2.Use as dust suppressant.
Lignosulfonate binds the road dust surface particle, when evaporate it will become the high-viscosity, naturally sticky material traps dust particles, then after sun heat will make a water resistant durable dust control surface.
3.Animal Feed AdditivesTo feed a variety of complex molecular nutrients fully decomposed and a good organic combination, increase gastrointestinal function, and promote the role of protein assimilation.
To improve the permeability of animal cell membrane and protoplasm, the muscle cell interstitial water content and cell water content increased, the phenomenon of pig hair skin and tender skin caused by this.
The sulfite process produces wood pulp which is almost pure cellulose fibers by using various salts of sulfurous acid to extract the lignin from wood chips in large pressure vessels called digesters.
The salts used in the pulping process are either sulfites (SO3 2−) or bisulfites (HSO3−), depending on the pH.
In this case, the counterion is Ammonium (NH4+).
The cooking liquor is prepared by adding the counter ions as hydroxides or carbonates.
The relative amounts of each species present in the liquid depend largely on the relative amounts of sulfurous used.
For Monovalent (M+) hydroxides, MOH:
SO2 + MOH
MHSO3 + MOH → M2SO3 + H2O
Sulfite pulping is carried out between pH 1.5 and 5, depending on the counter ion to sulfite (bisulfite) and the ratio of base to sulfurous acid.
The pulp is in contact with the pulping chemicals for 4 to 14 hours and at temperatures ranging from 130 to 160 °C (266 to 320 °F), again depending on the chemicals used.
Chief among sulfite process byproducts are lignosulfonates, which find a wide variety of industrial uses.
Ammonium Lignosulphonate is recovered from the spent sulfite by decanting (to remove insoluble material) and evaporation, the latter to increase the solids content to around 50%.
The solids content of the original material recovered from the spent sulfite liquor is less than 10%.
Further processing may involve adjusting the pH and spray drying, depending on the target industrial application.

Industry Uses
Ammonium Lignosulfonate provide three basic functions in dyestuff compositions:
1.Ammonium Lignosulfonates assist in reducing the dye particles to a fine size;
2.Ammonium Lignosulfonates maintain a dispersing medium for the dyestuff; and
3.Ammonium Lignosulfonates are used as a diluent.
The advantages of employing sulfonated lignins as dispersants in dyestuff compositions are based on their unique physical properties which include good compatibility with many dye systems, outstanding dispersant characteristics at ambient and elevated temperatures, and availability.
There are certain disadvantages in employing lignins, whether they are sulfite lignins or sulfonated kraft lignins, as dispersants.
Negative factors in the use of such lignins as dyestuff additives relate to problems of high inorganic salt content, i.e., electrolyte content, when lowered in pH, foaming, high pH, fiber staining, poor heat stability, and high viscosity.
These adverse properties are troublesome to dyers and many attempts have been made to overcome these and other disadvantages.
