| titleOfInvention | The production method of spherical cellulose acetate butyrate |
| abstract | The invention belongs to organic acid acetic Mierocrystalline cellulose manufacturing technology field, be specifically related to the production method of spherical cellulose acetate butyrate.The present invention, in order to solve the low technical problem of product yield, provides a kind of production method of spherical cellulose acetate butyrate, comprises the following steps: a, by the acetic acid process of velvet-like wood pulps or vinegar fine level purified cotton; B, by cooling after the mixing of butyryl oxide, acetic anhydride and the vitriol oil, the velvet-like wood pulps after process or the fine level purified cotton of vinegar are put in the mixed solution of above-mentioned cooling, then adds solvent acidylate; C, in acylation reaction liquid, add hydrolyzed solution hydrolysis, then to neutralize; D, precipitating, after sclerosis, obtain spherical cellulose acetate butyrate product by solid-liquid separation, washing, boiling, drying.Method provided by the invention effectively can reduce the apparent viscosity of reaction solution material, improves the mixed effect of material, improves its reactivity worth, improves reaction yield. |
