Sulfation Kinetics in the Preparation of Cellulose Sulfate

Abstract

Abstract: In the established apparatus, the conversion ratios of cellulose sulfation (X) under
different sulfation conditions were measured. The range of temperature is from -5 ℃ to +5
℃, and the H2SO4 concentration is from 3.1 mol× L-1 to 4.5 molL-1. The experimental
results were used for the establishment of the kinetic model for cellulose sulfation. With
the model X values and yield of NaCS Y can be calculated, thus the reaction in accordence
with H2SO4 concentration was determined to be third order3.

Key words: kinetic model, cellulose sulfate, microcapsule
