    摘要： A process for the continuous transesterification of C.sub.6 -C.sub.22 fatty acid lower alkyl esters, particularly methyl esters, with polyhydric C.sub.2 -C.sub.5 alcohols, particularly glycerol, in a reaction column comprising a rectifying and reaction section, alkaline catalysts and polyhydric alcohol are introduced into the upper part of the reaction column and boiling fatty acid methyl ester is introduced into the middle part of the reaction column. The product collected in the sump of the column is removed, heated and returned to the lower part of the reaction column. Product is removed from the sump. Lower alkanols passing from the reaction column section to the rectifying section are rectified. The reaction column is operated in boiling equilibrium in its lower part and predominantly in an absorption/desorption equilibrium in its upper part.

    摘要： The invention relates firstly to a discontinuous process for conducting a heterogeneously catalyzed reaction taking place at elevated temperature, in which heat-sensitive products are formed, a heat transfer unit (4) different from the reactor (1) being used for heating and a fixed-bed catalyst (3) being used as the catalyst and the reaction mixture being continuously circulated in succession through the catalyst (3) and then through the heat transfer unit (4). The problem to be solved in this process is to avoid losses of catalyst and product and to shorten the batch time and, optionally, the reaction time in accordance with German patent applications P 38 13 612.0 and P 38 26 320.3. The invention also relates to a plant for the discontinuous heterogeneously catalyzed production of heat-sensitive products at elevated temperature comprising a reactor (1), characterized by a heat transfer unit (4) arranged outside and connected to the reactor (1), a catalyst container (3) containing a fixed-bed catalyst preceding the heat transfer unit and a pump (2) for continuously circulating the reaction mixture in succession through the catalyst (3) and then through the heat transfer unit (4).

    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.

    摘要： 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. The olefinic phase passes successively through reaction stages I to n while the acid water, after reaction stage (n-1), passes through reaction stages (n-2) to 2 in counter flow to the olefin phase and then through stages n and 1, the reaction temperature being maintained in the range from 50.degree. to 80.degree. C. in the reactors and in the range from 15.degree. to 60.degree. C. in the phase separators.

    摘要： A process for the production of triglycerides of C.sub.1 -C.sub.4 alkyl esters of C.sub.6 -C.sub.22 fatty acids:a) where dry sodium carbonate catalyst is dissolved in glycerol and mixed with a molar excess of preferably the methyl ester of C.sub.6 -C.sub.22 fatty acid at a temperature between about 150.degree. C. and 250.degree. C. at less than atmospheric pressure and under substantially anhydrous conditions to produce an initial reaction mixture containing the corresponding triglycerides of said fatty acids, and partially reacted glycerol with unreacted hydroxyl groups (OH values 10-40),b) thereafter, a portion of the initial reaction mixture is reacted with additional C.sub.1 -C.sub.4 alkyl ester of C.sub.6 -C.sub.22 fatty acid under conditions to achieve substantially full conversion of said unreacted hydroxyl groups (OH values of 5 or less), andc) a product containing the corresponding triglycerides of said fatty acids is separated from unreacted alkyl ester and from the sodium carbonate catalyst. Improved light colored triglyceride products are achieved and can be separated readily from the sodium carbonate catalyst by filtration.
