Method for epoxidation of rape-seed oil in reaction with peracetic acid in-situ

摘要

method epoksydowania rapeseed oil, reaction with acid nadoctowym "in situ", produced during the mixing glacial acetic acid with hydrogen peroxide in the presence of strongly acidic kationitu, mole ratio of acetic acid to the unsaturated bonds 0.5 0.9: 1, peroxide water ru to quantities of unsaturated bonds 1.5 - 2.0: 1, characterized by that,the hydrogen peroxide is introduced so as to maintain a constant temperature reaction, that is, for 20 to 30 minutes. hydrogen peroxide is introduced during the intensive mixing, which measured turnover of 1600 to 2000 rpm stirring and continue mixing for 2 to 6 hours after the end of the introduction of hydrogen peroxide.the mixture poreakcyjnu0105 cools to ambient temperature, is filtered out kationit, washed him ethyl ether. the filtrate and liquid layer organic product poreakcyjnego and is washed with water to obtain a zdemineralizowanu0105 inert solution przemywaju0105cego at ph = 7.strongly acidic kationit on the filter is washed with ethyl ether in a quantity at least equal to three of his bed volumes. kationit is used in quantities of from 15 to 20% in relation to the rapeseed oil. the reaction is at a temperature between 50 - 65u00b0c.
