Once the cellulose is purified, it undergoes a critical step known as etherification. In this process, the hydroxyl groups on the cellulose chain are chemically modified to form methylcellulose and hydroxypropylcellulose. The reaction is typically carried out using a mixture of dimethyl sulfate or monochloroacetic acid as methylating agents and propylene oxide as the hydroxypropylating agent. The reaction conditions, including temperature, concentration, and time, play a significant role in determining the degree of substitution, which in turn influences the properties of the final product The reaction conditions, including temperature, concentration, and time, play a significant role in determining the degree of substitution, which in turn influences the properties of the final product
