摘要： In modern processes for the preparation of cellulose ethers containing one or more types of substituents (such as MC, CMC, HEC, HPC, MHEC or EHEC), cellulose is reacted with etherifying agents in the presence of water, base and a mixture of preferably inert organic solvents (as a dispersing auxiliary). Dimethoxyethane (ethylene glycol dimethyl ether) and at least one organic solvent selected from the group including alkanols, alkane diols and alkoxy alkanols (for example, methanol and/or isopropanol) are employed in the mixture of organic solvents used for these syntheses, particularly in quantities of 1 to 30 parts by weight per 1 part by weight of cellulose.

摘要： A process for purifying or working-up a mixture containing water, water-soluble salts, organic ions and organic solvents, particularly mixtures of water, NaCl, Na glycolate and aliphatic alcohols such as methanol or isopropanol, by separating the mixture into its components using acidic and/or basic ion exchangers, in particular, using weakly basic anion exchangers after optionally adjusting the pH of the mixture to an acid value. The process is especially suited for purifying liquid reaction media and/or washing media from the production of polysaccharides, such as cellulose ethers or starch ethers containing sodium-carboxymethyl group substituents, which are prepared from polysaccharides, an alkali metal hydroxide and monochloroacetate ions in a medium containing water and at least one organic solvent.

摘要： Modified cellulose ethers are obtainable by admixing cellulose ethers having free OH groups with chemical compounds containing at least one aldehyde group and at least one acid group, and then reacting the acid groups and the aldehyde groups with the free OH groups of the cellulose ethers. The cellulose ethers modified in this way are distinguished by an improved lump-free stirrability into water and a salvation delay which can be adjusted in a targeted manner.

摘要： Disclosed is a process for preparing water-soluble sodium carboxymethyl cellulose (NaCMC), including mixed ethers of NaCMC, by etherifying cellulose with alkyl monochloroacetates in an aqueous-alkaline dispersion containing at least one organic solvent. In the process, cellulose is first alkalized in an aqueous-alkaline dispersion, which optionally already contains the organic solvent. Subsequently, the alkali cellulose is reacted essentially with an alkyl monochloroacetate as the etherifying agent, in the presence of the organic solvent.
