Lignosulfonates Application

What is Lignosulfonate

Lignosulfonates are when traded a brown amorphous powder. They have no odour and they are not hygroscopic. They form colloidal solutions or dispersions with water but are not soluble in organic solvents.

Lignosulfonates are biopolymers; they are salts of lignosulfonic acid that has been formed when pulp is manufactured by the sulphite method. The lignosulfonates are of varied composition because the woods are different, the extent of the lignin degradation can be different and a different number of sulfonic groups can have been added. Lignin is a polymer with a most varied length and composition, a fundamental structure being hydroxyphenyl propane.

It contains many phenolic rings and methoxy groups, the figure gives one example. The distribution of unpolar and polar groups, including the hydroxyl and sulfonic acid groups formed at the degradation, decides the properties of the particular lignosulfonate.
