| titleOfInvention | Process for recovering an esterified cellulose ether from a reaction product mixture |
| abstract | A process for recovering an esterified cellulose ether from a reaction product mixture obtained from a reaction of (a) a cellulose ether with (b) an aliphatic monocarboxylic acid anhydride or a di- or tricarboxylic acid anhydride or a combination of an aliphatic monocarboxylic acid anhydride and a di- or tricarboxylic acid anhydride, comprises the steps of (i) contacting the reaction product mixture with an aqueous liquid and precipitating the esterified cellulose ether from the reaction product mixture, and (ii) isolating the precipitated esterified cellulose ether from the mixture obtained in step (i). Tackiness of the esterified cellulose ether can be reduced when before or in step (i) a stearic acid salt is dispersed in the reaction product mixture, the aqueous liquid or a combination thereof at a weight ratio of at least 0.04 weights part stearic acid salt per weight part of cellulose ether utilized for producing the esterified cellulose ether. |
