    摘要： A process for the isolation and purification of essentially fatty acid mixtures, which in addition to the methyl branched fatty acids contain saturated and unsaturated, respectively straight chain as well as methyl branched, unsaturated fatty acids, in which the industrial fatty acid mixtures are first hydrogenated by catalysis and then the methyl branched saturated fatty acids are separated, and in which before the hydrogenation if necessary, a separation by the hydrophilization process is provided, this process produces the desired products with a high yield and purity.

    摘要： The epoxidation of terminally and/or internally olefinically unsaturated hydrocarbon compounds which are liquid at 50.degree. to 100.degree. C. and at atmospheric pressure (oil phase), in which the oil phase is treated with an acid phase containing acetic acid, hydrogen peroxide and peracetic acid in aqueous solution, after which the aqueous acid phase is separated from the oil phase, the peracetic acid in the aqueous acid phase is regenerated and the regenerated aqueous acid phase is returned to the epoxidation reactor. Epoxidation is carried out using an aqueous acid phase containing at most about 10% by weight of peracetic acid, and the peracetic acid content in the aqueous acid phase is reduced by at most about 50%, based on the peracetic acid content of the aqueous acid phase used, after a single passage through the epoxidation stage. After separation from the oil phase, the aqueous acid phase preferably is cooled before regeneration.
