  • Hydroxyethyl cellulose powder is a stable though hygroscopicmaterial.
    Aqueous solutions of hydroxyethyl cellulose are relatively stableat pH 2–12 with the viscosity of solutions being largely unaffected.However, solutions are less stable below pH 5 owing to hydrolysis.At high pH, oxidation may occur.
    Increasing the temperature reduces the viscosity of aqueoushydroxyethyl cellulose solutions. However, on cooling, the originalviscosity is restored. Solutions may be subjected to fre

  • Stable. Incompatible with strong oxidizing agents, acid chlorides, acid anhydrides

Usage

Hydroxyethyl cellulose is generally used as a thickener, protective agent, binder, stabilizer and additives for the preparation of emulsions, gels, ointments, lotions, eye clears, suppositories and tablets, and also used as hydrophilic gelling agents. Glue, matrix materials, preparation of matrix-type sustained-release preparations, and can also be used as stabilizers in food.

Production Methods

Alkali cellulose is a natural polymer, each fiber ring containing three hydroxyl, the most active hydroxyl reaction, the formation of hydroxyethyl cellulose. The raw cotton linters or the refined pulp is soaked in the caustic soda of 30, and the press is taken out after half an hour. Crushed to an alkaline water content of 1: 2.8. Crushed alkali cellulose into the reactor, closed, vacuum, nitrogen, repeat the vacuum filling nitrogen inside the kettle to replace the air to do. Press into the pre-cooling of ethylene oxide liquid, the reactor jacket into the cooling water, control reaction 25 ℃ 2h, in hydroxyethyl cellulose crude. Crude alcohol with alcohol to wash, add acetic acid and pH 4-6, plus glyoxal cross-linked aging. And then washing with water, centrifugal dehydration, drying, milling, in hydroxyethyl cellulose. Raw material consumption (kg / t) Cotton linter or low meal 730-780 Liquid caustic (30) 2400 Ethylene oxide 900 Alcohol (95) 4500 Acetic acid 240 Glyoxal (40) 100-300.
