Abstract
N-Acylated partially deacetylated chitin (DAC-88) derivatives were prepared via ring-opening reactions with various cyclic acid anhydrides in aqueous MeOH system. N-Alkylation of DAC-88 were also performed in aqueous MeOH wit h various aldehydes, monosaccharides, and disaccharides. The water solubili ty of N-acylated and N-alkylated chitosan derivatives at various pHs were s tudied. (C) 1999 Elsevier Science Ltd. All rights reserved.
