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.

Изобретение относится к химической технологии и касается получения хитозана. Хитозан получают обработкой природного сырья декальцинированием, депротеинизацией и деацетилированием гидроксидом натрия. Дополнительно проводят отбеливание перекисью водорода или гипохлоритом натрия. Декальцинирование ведут в две стадии, а перед деацетилированием удаляют воду. Приведены конкретные параметры процесса.The invention relates to chemical technology and for the production of chitosan. Chitosan is obtained by treating natural raw materials with decalcification, deproteinization and deacetylation with sodium hydroxide. Additionally, bleaching is carried out with hydrogen peroxide or sodium hypochlorite. Decalcification is carried out in two stages, and water is removed before deacetylation. Specific process parameters are provided.
