Once purified cellulose is obtained, the next stage involves the etherification reaction, which is central to the production of HEC. In this process, the purified cellulose is treated with ethylene oxide, a chemical compound that reacts with the hydroxyl groups present in the cellulose structure. This reaction occurs in a controlled environment, often using solvents and catalysts to facilitate the process. The temperature and pressure during this stage are critical parameters, as they directly influence the degree of substitution of the hydroxyethyl groups on the cellulose backbone. An optimized reaction conditions ensure that the HEC produced has the desired viscosity and solubility characteristics.
