    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： 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： For the production of fatty acid esters of short-chain, aliphatic alcohols by the catalytic transesterification of natural fats and/or oils containing free fatty acids (oil phase) with the corresponding monoalcohols, the oil phase is subjected to preliminary esterification with the monoalcohols in the presence of acidic esterification catalysts at temperatures no higher than 120.degree. C. and under pressures no higher than 5 bars and in the presence of a liquid entraining agent substantially immiscible with the oil phase, after which the reaction product is separated into an entraining agent phase containing the acidic catalyst and water of reaction and the treated oil phase, the oil phase is then subjected to transesterification while the acidic catalyst-containing entraining agent phase is returned, after at least partial drying, to the preliminary esterification stage. By this process, fats and/or oils with acid numbers of up to 60 can be processed in the preliminary esterification stage to give an oil phase having a low acid number.
