Abstract: A process for producing oleochemical polyols comprises the steps of epoxidizing unsaturated oil using an organic acid together with oxygenated water or a per-acid to obtain epoxidized oil; washing the epoxidized oil with salt water to remove unused organic acid together with oxygenated water or a per-acid; neutralizing acidic condition of the washed epoxidized oil with a base; washing the neutralized epoxidized oil with a salt solution until the pH of the neutralized epoxidized oil reaching 6.5 to 7.5 to removed the base residue; drying the washed neutralized epoxidized oil under vacuum; and reacting the washed neutralized dried epoxidized oil with polyhydric alcohol in the presence of boron trifluoride-diethylether complex to produce the oleochemical polyols. The oleochemical polyols are then subjected to the same washing, neutralizing, washing and drying process as in preparing the washed neutralized dried epoxidized oil.

Abstract: In a multistage process for the continuous epoxidation of double bonds of terminal and non-terminal olefins containing more than 12 carbon atoms, unsaturated higher fatty acids and their lower alkanol and lower alkanediol esters and also unsaturated fatty alcohols containing from 8 to 18, preferably 18, carbon atoms and triglycerides of higher fatty acids including unsaturated fatty acids, preferably soyabean oil, using performic acid formed in situ from hydrogen peroxide and formic acid, the reactants, olefin and hydrogen peroxide/formic acid, are passed at ambient pressure in cross-counter flow through an at least three-stage reaction cascade. The olefinic phase is introduced into the first reaction stage, the hydrogen peroxide and the formic acid are introduced in separate streams into the penultimate reaction stage and the olefin phase and the hydrogen peroxide/formic acid phase (acid water phase) are separated from one another in a phase separator after each reaction stage.
