Abstract
FIELD: chemical technology. SUBSTANCE: chitosan is prepared by treatment of natural raw materials followed by decalcination, deproteinization and deacetylation with the help of sodium hydroxide. Additionally whitening with the help of hydrogen peroxide or sodium hypochlorite takes place. Said decalcination is carried out in two stages, before said deacetylation water being removed. EFFECT: improves efficiency of the method.
