FIELD: cellulose derivatives production.
SUBSTANCE: object of invention is production of sodium-carboxymethylcellulose product from cellulose-containing vegetable stock without separation cellulose from lignin, lipids, and resinous substances present in plant tissues. Method according to invention comprises treatment of vegetable stock, namely straw, with monochloroacetic acid sodium salt on flow-type vibration-centrifugal mill run in continuous mode at acceleration of elastic grinding bodies 100-200 m/s-1, addition of aqueous sodium hydroxide solution to resulting powder composite, and stirring. Starting components are taken in following molar proportion: cellulose/monochloroacetic acid salt/sodium hydroxide/water = 1:(1.7-2.1):(3.0-3.5):(8-12).
EFFECT: increased viscosity of aqueous suspension prepared from sodium-carboxymethylcellulose product.
