Abstract

This study depicts the preparation of a new amino cellulose derivative of cellulose extracted from bagasse. 2,3-dialdehyde cellulose (DAC) with 60% degree of oxidation was prepared from cellulose by periodate oxidation. The obtained DAC was functionalized by Schiff base reaction with several amino acids up to 2.55% nitrogen content. Aliphatic/Aromatic, Mono/Dibasic, and Mono carboxylic/Dicarboxylic amino acids were investigated for the Schiff base reaction. FTIR spectra confirmed the successful introduction of the amino acids functional groups (carboxyl and amino groups). The successful interaction of amino acids with DAC composites were characterized and confirmed by elemental analysis, EDAX, TEM, SEM, XRD and TGA. A green method for preparation of amino acids functionalized 2,3-dialdehyde cellulose could be obtained in an efficient manner by controlling the amino acid type and degree of substitution while producing the DAC composites.
