ACÉTATE DE CELLULOSE ET PROCÉDÉ DE PRODUCTION D'ACÉTATE DE CELLULOSE

摘要

To provide cellulose acetate that exhibits excellent hue even though it is produced by using low grade pulp having a particularly low α-cellulose content, and also achieves excellent moldability and excellent production efficiency of a molded article. A method for producing cellulose acetate is also provided, the method that can provide cellulose acetate with excellent stable productivity and production efficiency without passing through steps such as extraction. The cellulose acetate of the present invention includes xylose with a molar content rate of greater than 7.0 mol% and not greater than 15 mol% in a sum of molar contents of xylose, mannose, and glucose; and has a hue of not less than 0.60 cmand less than 0.80 cmat a wavelength of 430 nm by absorptiometry; and a 6% viscosity of not greater than 160 mPa•s.
