    • Hydroxyethyl cellulose powder is a stable though hygroscopic material.
      Aqueous solutions of hydroxyethyl cellulose are relatively stable at 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 aqueous hydroxyethyl cellulose solutions. However, on cooling, the original viscosity is restored. Solutions may be subjected to fre

    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.
