| titleOfInvention | Process for the preparation of water-soluble mixed cellulose ethers |
| abstract | The process for the preparation of mixed cellulose ethers proceeds in steps a) alkalizing the cellulose, b) etherifying the alkali cellulose in the presence of a base with at least one etherifying agent which requires a catalytic and substoichiometric amount of a base for the reaction with cellulose, and c) after increasing the Base amount of further etherification of the cellulose ether produced in this way with at least one etherifying agent which requires an at least stoichiometric or an increased catalytic and sub-stoichiometric amount of base for the reaction with cellulose, at least one inert organic solvent as a dispersing aid and in all of them in at least one of the stages Levels of water is present. The mixed etherification leads to a water-soluble product, and the organic solvent used is dimethoxyethane, an alkanol, an alkanediol and / or an alkoxyalkanol. The process is used in particular for the production of methyl-hydroxyethyl or methyl-hydroxypropyl cellulose. |
