At present, the source of most sulfonated modified lignosulphonate products which at home and abroad is main abtracted from modified sulphite paper pulping waste liquor and alkaline papermaking pulping black liquor. Compared with alkaline papermaking pulping black liquor lignosulphonate product,sulfite method Paper pulping waste liquor of the modified products have the better Water-soluble, dispersion, surface

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

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

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 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
