PREPARATION METHOD OF ACETYLATED CELLULOSE ETHER, AND ACETYLATED CELLULOSE ETHER PREPARED THEREBY |
| 摘要 |
Disclosed are a method of preparing acetylated cellulose ether, and acetylated cellulose ether prepared thereby. Here, the disclosed method of preparing the acetylated cellulose ether includes dissolving acetylated cellulose ether in an organic solvent to obtain a mixture comprising a solution of the acetylated cellulose ether; removing an insoluble component that is insoluble in the organic solvent from the mixture; and adding the mixture to water to precipitate the acetylated cellulose ether. The acetylated cellulose ether prepared thereby has a turbidity of less than 40 formazin turbidity units (FTU). |
