| Abstract: | This paper reports the conditions for preparation of Acetylchitin(ACC),Hexanoylchitin(HCC),Dodecanoylchitin(DCC) and N-Benzylhexanoylchitosan(NBHC) by homogenuous methods in methanesulfonic acid-acyl chloride mixtureat low temperature.The solubilities of all products in different kinds of organic solvents are also studied.All products of ACC,DCC, HCC and NBHC are soluble inmethanoic acid,DCC,HCC is soluble in ethanol,and NBHC is also soluble in ethylether,phenol and etnyl acetate. |
