Esterification of cellulosic textiles with sorbic acid in the presence of trifluoroacetic anhydride using controlled cellulose-acid-anhydride ratios
摘要:
This invention relates to the production of partial cellulose esters with improved crease recovery through esterification of cellulose with unsaturated fatty acids in the presence of trifluoroacetic anhydride (TFAA) in benzene solution.
