  • Once the cellulose is activated, the hydroxyethylation reaction can take place. Ethylene oxide is added to the activated cellulose under controlled conditions, typically in a closed reactor system. The reaction occurs at elevated temperatures and pressures to ensure that the ethylene oxide effectively reacts with the hydroxyl groups of cellulose, resulting in the substitution of hydroxyethyl groups into the cellulose backbone. The reaction time, temperature, and ratio of reagents are meticulously controlled to achieve the desired degree of substitution, which influences the solubility and viscosity of the final product.
