| titleOfInvention | Cellulose acetate, cellulose acetate production method and production apparatus |
| abstract | An object is to provide a cellulose acetate excellent in hue even when a low-grade pulp is used. Step (1) of crushing wood pulp, step (2) of bringing the crushed wood pulp into contact with acetic acid and pretreatment, and after the pretreatment, the wood pulp is reacted with acetic anhydride to produce acetyl The step (3) of hydrolyzing, the step (4) of hydrolyzing the cellulose acetate obtained by the acetylation, and the step (5) of precipitating the cellulose acetate having the degree of acetyl substitution adjusted by the hydrolysis, The method for producing cellulose acetate, wherein, in the hydrolysis step (4), the oxygen concentration in the hydrolysis reaction system is 3% or less. |
