OBTAINING COTTON SEED OIL EPOXIDIZED USING AN WEAK ACID

Abstract

In this study, parameters which influence the chemical modification under mild conditions using a weak organic acid, fatty acids of unsaturated oil, cottonseed to produce epoxidized oil, which is a useful precursor in obtaining resins epoxy industrial importance, were evaluated. We studied the following reaction parameters: concentration of acetic acid, hydrogen peroxide, catalyst and solvent, as well as temperature, agitation rate and reaction time. The results showed that the agitation and temperature are the parameters which influence the modification of unsaturated fatty acids. Studied conditions allowed obtaining up to 70% relative conversion of oxygen-oxirane from cottonseed oil.
