Abstract

Abstract:

The paper studied the results of benzyl isocyanate with n-propanol, water and cellulose with different moisture content (MC) by FTIR, in which the IR bands were identified. The reaction product of isocyanate and cellulose carbamate. With MC of cellulose increasing, the reaction of isocyanate and cellulose decreases while the reaction of isocyanate with water increases. When the MC of cellulose is 9.78%, most of isocyanate reacts with water absolutely and forms dibenzylurea.

Key words: Benzyl isocyanate, Cellulose, Moisture content, Competitive reaction, IR spectroscopy
