Method for preparing hydroxypropyl methylcellulose acetate succinate (hpmcas) grains having controlled grain size distribution, and hpmcas powder |
| abstract |
Disclosed are a method for preparing hydroxypropyl methylcellulose acetate succinate (HPMCAS) grains and HPMCAS grains. The disclosed method for preparing HPMCAS grains comprises: a step (esterification step) of esterifying hydroxypropyl methylcellulose (HPMC), acetic anhydride, and succinic anhydride in a reaction medium in the presence of a catalyst so as to obtain a reaction solution containing HPMCAS; and a step (granulating step) of putting the reaction solution into water continuously or intermittently so as to form grains. |
