OXIDATION KINETICS OF CARBOXYMETHYLCELLULOSE
Abstract
Considering the fact that researches on natural polymers are increasing today, this article aims to determine the optimal conditions for obtaining dialdehyde carboxymethylcellulose (DCMC) samples based on sodium carboxymethyl cellulose (Na-CMC) with a high molecular mass and a large amount of aldehyde groups. By carrying out the periodic oxidation reaction in the presence of ultra-high frequency (UHF) rays, the oxidation reaction was carried out for 10 minutes, and DCMC samples containing 82% aldehydes were obtained.
