Water-Soluble Chitosan

Chitosan Sulfate

Introduction:As a novel solid catalyst, Chitosan sulfate has great significance in esterification reaction. Using Chitosan sulfate instead of sulfuric acid in esterification reactions has advantages of high catalytic activity, less consumption, good selectivity, zero side reaction and high product yield, etc. Moreover, using Chitosan sulfate instead of sulfuric acid in esterification reactions also has characteristics of simple and convenient after-treatment, stable performance of continuous catalysis, zero corrosion of equipment and less waste discharge. Therefore, Chitosan sulfate is a kind of green catalyst with good development prospects.

Characters:off-white powder; insoluble in water; organic polymer salt.
