Aggregate formation and surface activity of partially deacetylated water-soluble chitin

Aggregate formation and surface activity of partially deacetylated water-soluble chitin Water-soluble chitin (WSC), partially acetylated, was prepared by using N-acetylation in mild conditions. The aggregation behavior of WSC in aqueous solution was investigated. the results showed that the surface tension decreased with increasing WSC concentration in the high dilute solution, the critical aggregation concentration was about 0.010 g/ml. The degree of deacetylation had an obvious effect on the surface tension. Introduction of acetyl favored aggregation formation. The possible aggregation mechanism of WSC in water was attributed to the molecules’ conformation transition, resulting in change of intra- and inter-molecular interactions such as hydrogen bonding and hydrophobic interaction. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Water-soluble chitin (WSC), partially acetylated, was prepared by using N-acetylation in mild conditions. The aggregation behavior of WSC in aqueous solution was investigated. the results showed that the surface tension decreased with increasing WSC concentration in the high dilute solution, the critical aggregation concentration was about 0.010 g/ml. The degree of deacetylation had an obvious effect on the surface tension. Introduction of acetyl favored aggregation formation. The possible aggregation mechanism of WSC in water was attributed to the molecules’ conformation transition, resulting in change of intra- and inter-molecular interactions such as hydrogen bonding and hydrophobic interaction.
