FIELD: technological processes; chemistry.
SUBSTANCE: invention relates to method of producing low-molecular water-soluble chitin. Method provides for treatment of high-molecular chitin powder with particle size of 10-100 mcm and viscosity-average weight of 1,000 kDa. Treatment is carried out in electronic beam plasma-chemical reactor with installed inside the working chamber reactor electromagnetic system in low-temperature strongly nonequilibrium electron-beam oxygen plasma, or steam, or nitrogen for 1-60 minutes at pressure of plasma forming medium 5-10 Torr, accelerating voltage 30 kV, current electron beam 1.5-2.5 mA, temperature in reaction volume of 50-90 °C.
EFFECT: invention allows to produce sterile low-molecular water-soluble chitin without formation of toxic side compounds emissions and drains, polluting environment.
