    摘要: A process for the production of fatty acid lower alkyl esters comprising the steps of: A) treating at least one fatty acid ester of glycerol with from about 0.3 to about 3% by weight, based on the weight of ester, of an acid at an elevated temperature; B) removing said acid from the treated fatty acid ester; and C) reacting the treated fatty acid ester with at least one lower aliphatic alcohol to transesterify the fatty acid ester.

    摘要: Fatty acid glycerides can be transesterified with lower aliphatic alcohols if the reaction is carried out in the presence of fatty acids corresponding to formula (II):R.sup.2 --COOH (II),in which R.sup.2 is an aliphatic hydrocarbon moiety containing 11 to 17 carbon atoms and 0, 1 or 2 double bonds. The products are distinguished by a low content of bound glycerol and a low acid value. Removal or neutralization of the catalyst is unnecessary because, after the transesterification, the fatty acids are also present in the form of their esters.

    摘要: C.sub.8-22 fatty alcohols are produced by a process which comprises contacting a triglyceride with hydrogen in the presence of a copper-zinc catalyst and in a reaction zone. The hydrogen pressure in the reaction zone is from about 200 to about 280 bar, the temperature of the entrance of the reaction zone is from about 200.degree. C. to about 230.degree. C., and the temperature of the exit of the reaction zone is from about 190.degree. C. to about 220.degree. C. The amount of 1,2-propanediol formed is optimized by the lower temperature of the exit portion of the reaction zone.

    摘要: The proposal is for unsaturated fatty substances with improved cold behavior obtained by (a) transesterifying a new low stearic (LS) sunflower oil with an oleic acid content of over 85 wt. % and a stearic acid content of under 3 wt. %, and (b) hydrogenating the resultant methyl esters in the prior art manner into the corresponding unsaturated fatty alcohols in the iodine number range from 90 to 100. The fatty substances are also distinguished by improved color and odor and are suitable for making fatty chemical products, e.g. alkoxylates, ether sulphates, sulphates and esters.

    摘要: Unsaturated fatty alcohols with 6 to 22 C atoms can be produced by directly hydrating deacidified and/or non-deacidified glyceride oils containing monounsaturated and/or polyunsaturated, straight chain and/or branched-chain fatty acids having 6 to 22 C atoms in the fatty acid residue, by applying a 30 to 100-fold excess of hydrogen in a pressure range from 50 to 300 bars, at temperatures from 200.degree. to 400.degree. C., to zinc-chrome-catalysts of the spinel type, while largely preserving the olefinic double bonds and with formation of propane and 1,2-propylene glycol.
