Title:
CELLULOSE ESTER COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2015/162787
Kind Code:
A1
Abstract:
This cellulose ester composition is characterized in containing a cellulose mixed fatty acid ester in which hydrogen atoms of the hydroxyl groups of cellulose are substituted by acetyl groups and C6-26 saturated aliphatic acyl groups, the cellulose ester composition being further characterized in that the C6-26 saturated fatty acid content corresponding to the C6-26 saturated aliphatic acyl groups is less than 0.1 wt% relative to the cellulose mixed fatty acid ester. This cellulose ester composition can be produced via, e.g., a step for heating a crude product of this cellulose mixed fatty acid ester together with a wash solvent and a step for separating the cellulose mixed fatty acid ester and the wash solvent.
