摘要: Developing highly environmentally friendly and cost-effective approaches for the chitosan production has paramount important in future technology. Deacetylation process is one of most importing steps to classify quality chitosan. This research aimed study best method deacetylation chitin considered by several factors like concentration base, temperature, time reaction method. From green chemistry point view, conventional refluxing relatively wasted energy compared another such as maceration, grinding sonication. The degree (DD) was studied sonication, resulted slightly increasing DD from 73.14 73.28% during 0.5 h 1 h. with various sodium hydroxide 60, 70 80% gave 73.14, 76.36 77.88% DD, respectively. Variation temperature at 40, 80 °C affected on 67.53, 72.84 73.14%, DD...
