3. Manufacturing Process for Hydroxy Methyl Propyl Cellulose

1. Alkalization ➔ 2. Etherification
(Propylene oxide & Methyl chloride) ➔ 3. Neutralization / Washing ➔ 4. Refining & Drying ➔ 5. Milling & Grading ➔ 6. Quality Testing
(ISO, ANSI, FDA) ➔ 7. Packaging & Logistics

Detailed Explanation: The process begins with alkalization of purified cellulose using a sodium hydroxide solution, forming alkali cellulose. This is followed by rotary etherification where propylene oxide and methyl chloride are introduced under controlled temperature (35–45°C) and pressure (0.3–0.7 MPa) for uniform group substitution.
The mixture is then neutralized, washed until salt-free, filtered, and dried under vacuum at 60–80°C. Final milling and grading ensure narrow particle size distribution and consistent viscosity.
Each batch is tested against ISO 9001:2015 and ANSI/ASTM D2363 (for viscosity/safety) before release.
