3、 Preparation of Hydroxyethyl Cellulose by Liquid Phase Method

The chemical formula of hydroxyethyl cellulose can be represented as \(C_2H_6O_2\) derived from the hydroxyethylation of cellulose. The process typically involves the treatment of cellulose fibers with ethylene oxide in the presence of an alkaline catalyst, which results in the substitution of hydroxyl groups on the cellulose backbone with hydroxyethyl groups. This modification enhances the solubility of cellulose in water, making it more versatile for various applications.

Moreover, RDP polymers find applications in the production of dry-mix mortars, such as those used for plastering or rendering. The addition of RDP enhances the performance of these mortars, including their water retention and open time, contributing to better workability and finish.

In the pharmaceutical industry, different grades of HPMC play pivotal roles in drug formulation. The selection of HPMC grade can influence drug release profiles, stability, and bioavailability. For instance, sustained-release formulations often utilize high-viscosity HPMC grades, which provide a controlled release of the active pharmaceutical ingredient (API) over an extended period. Conversely, immediate-release formulations may use lower viscosity grades to ensure that the drug is released rapidly upon ingestion.
