The key step in manufacturing hydroxyethyl cellulose is the hydroxyethylation reaction. This is performed by introducing ethylene oxide (EO) to the activated cellulose. Ethylene oxide is a small, cyclic ether molecule that can readily react with the hydroxyl groups present on the cellulose chains making it an ideal candidate for this process. The reaction typically takes place in a controlled environment, often at elevated temperatures and under specific pH conditions, to ensure proper interaction and substitution of the hydroxyl groups.
