Synthesis of mix chitin esters

Abstract

The aim of this study was the synthesis of chitin esters, which at a later stage could be used to produce antibacterial textiles. The esterification of chitin was carried out using butyric anhydride, succinic anhydride and methanesulfonic acid as a catalyst. The produced products were analysed by FTIR and NMR techniques and the dynamic apparent viscosity of the spinning solutions was examined. The products containing butyl and succinic anhydride in molar ratios 95/5 and 85/15 showed the best properties.
