Temperature-dependent etherification of cassava starch with CHPTAC for cationic starch production

Case Studies in Chemical and Environmental Engineering
This research explores utilizing abundant and economical cassava as a raw material for producing cationic starch in Indonesia. Cationic starch was synthesized by etherifying cassava starch with CHPTAC monomer at 50–90 °C. Successful cationic modification
