Cellulose acetate and method for producing cellulose acetate |
| abstract |
An object of the present invention is to provide cellulose acetate having a low total substitution degree of acetyl groups, a low degree of acetyl substitution at the 6-position relative to the acetyl substitution degrees of the 2- and 3-positions of the glucose ring, and excellent water solubility. Cellulose acetate having a total substitution degree of acetyl groups of 0.4 or more and 0.9 or less, the ratio of the acetyl group substitution degree at the 6-position to the above-mentioned total substitution degree of acetyl groups is 0% or more and 18% or less, and having a permeability of 660 nm in a 4 wt% aqueous solution The light rate is 5% or more. |
