MODIFICATION OF WOOD WITH FATTY ACIDS OBTAINED FROM SOAP STOCK

Abstract

The paper considers the study of obtaining fatty acids from soap stocks. The proposed method of chemical processing of soap stock was applied for the first time and is not found in the previously published literature on the problems of chemical processing of vegetable oil waste. The composition of the isolated fatty acids of soap stock was studied by mass spectroscopy and the main chemical characteristics of the obtained fatty acids were determined. The isolated fatty acids are valuable not only as a feed additive for livestock, but also as a raw material for the chemical industry, in particular for the production of cellulose esters. The resulting fatty acids were used in the acylation of wood to obtain cellulose esters. The paper considers the kinetic regularities of the reaction of wood acylation with fatty acids of soap stock and studies the optimal conditions for the synthesis of cellulose esters from wood depending on the temperature and time of synthesis. The resulting products were investigated by IR spectroscopy, which proved the formation of an ester bond in the products obtained. When studying the kinetic regularities of the acylation of wood with fatty acids, the energy parameters were calculated in accordance with the kinetics of heterogeneous processes, which include the acylation of wood.
