PHYSICOCHEMICAL PROPERTIES OF CHITIN ISOLATED FROM SHELL OF INDUSTRIAL CRABS OF VARIOUS SPECIES

Abstract

Differential thermal analysis was carried out over the range of –190 ÷ 400 °С on six samples of chitin from shells of industrial crabs of various species. All samples of the chitin have several relaxation transitions of endothermal character (g1-, g2-, β- and γ-).
