Ammonium Lignosulfonate Used in Dyes industry
It is known to employ lignosulfonate compounds, including sodium salts of lignosulfonates, as an additive, such as a dispersant, in textile dyestuffs and printing pigments. Such lignosulfonate compounds are generally produced as a by-product of the wood pulping industry by either the sulfite or kraft process. Such sulfonated lignin products provide three basic functions in

Lignosulfonate function for emulsion
Lignosulfonate, also referred to as sulfonated lignin, is a product of the wood pulping process. Initially considered as a waste material, refined lignosulfonate nowadays constitutes a viable alternative to synthetic chemicals in many applications.Among others, it is used in dispersant formulations in concrete, for rheology control of drilling fluids and coal–water slurries, and as a

Salt tolerance of sodium lignosulfonates and the emulsion stabilization efficiency
Methods were adapted to investigate the salt tolerance of sodium lignosulfonates and their emulsion stabilization efficiency. In addition, droplet size distributions and lignosulfonate effect on IFT were studied. The results were furthermore discussed with respect to the analytical data provided with the samples, more specifically hydrophobicity and average molecular weight. The trend in salt tolerance

About Lignin
Lignin is the largest reservoir of aromatic compounds on earth and has great potential to be used in many industrial applications. Alternative methods to produce lignosulfonates from spent sulfite pulping liquors and kraft lignin from black liquor of kraft pulping process are critically reviewed herein. Furthermore, options to increase the sulfonate contents of lignin-based products

Molecular Structure of Sodium Lignosulfonate
The molecular structure and properties of four sodium lignosulfonates (LSs) derived from pulping or bioethanol production were evaluated and compared. SXP and SAL were produced by sulfite pulping and sulfonation reaction of lignin from alkali pulping of poplar, respectively. LS-180 and LS-150 were from sulfite pretreatment to overcome recalcitrance of lignocelluloses (SPORL) pretreatment of lodgepole

Lignosulfonate used in Dust control
Lignosulfonate could work as naturally binder as its original form of lignin to bind the cellulose and fiber,so it can be used binding agent in pellets or compressed materials,also could used as dust control agent,which will be much more environment friendly and lower cost compared with Chloride. How lignosulfonate control the dust Lignosulfonate binds the
