1.Production process of hydroxypropyl methylcellulose (1) 2.Production process of hydroxypropyl methylcellulose (2) 3.Production process of hydroxypropyl methylcellulose (3) 4. Homogeneous method (dissolution method) production process of HPMC In the alkali leaching, slurry and gas-solid processes, the reaction system is in a multiphase state, which aggravates the uncertainty of the product structure. Structure determines the properties,
