| titleOfInvention | Method of chitosan production |
| abstract | FIELD: medicine; pharmacology. n SUBSTANCE: offered invention concerns medicine and pharmacology, exactly to method of Chitosan production. Method includes milling of natural chitin-containing raw material, alternating by turn three stages of raw material deproteinisation, and three stages of decalcification, deproteinisation stages are carried out by sodium hydroxide solution of concentration 3-5% produced by diaphragm electrolysis method within 3-4 hours at temperature 60-65°C; decalcification stages are performed by 3-5% hydrochloric acid solution at temperature 20-25°C within 1-3 hours; deacetylation is performed by 49-55% sodium hydroxide produced by diaphragm electrolysis method; deproteinisation and decalcification stages are performed in series connected six steel devices with internal glass-enamel coating, equipped with stirrers, thermopools, connections for reagents feeding and disposal, jackets for reactionary mass cooling and heating. Afterwards deacetylation follows with 49-55% sodium hydroxide produced by diaphragm electrolysis method. Process is conducted at temperature 95-105°C within 7-9 hours and followed by washing, spinning and drying of finished Chitosan. n EFFECT: production of high-clean Chitosan. |
