Dibutyrylochityna
WebDibutyrylochitynę otrzymuje się w wyniku reakcji estryfikacji bezwodnika/masłowego z chityną. Otrzymana w taki sposób dibutyrylochityna (DBCH) stanowi surowiec wyjściowy do formowania z niej włókien. Włókna DBCH formowano z roztworów sporządzonych w bezwodnym alkoholu etylowym. http://yadda.icm.edu.pl/yadda/element/bwmeta1.element.baztech-5a711cd4-ddb6-49b8-a388-46f2d1f37101
