A process for preparing long chain saturated or unsaturated oxygenated compounds. The process for the preparation of long-chain saturated or unsaturated oxygenated compounds having from 20 to 36 carbon atoms, selected from the group consisting of polycosanoic acids, their alkyl esters, polycosanols and corresponding compounds having an unsaturated hydrocarbon chain comprises the operation of reacting, in accordance with the Wittig or Peterson olefination reaction, a phosphorus ylide RP(Ar)3, wherein R is a saturated or unsaturated hydrocarbon chain containing one or more ethylenic and/or acetylenic unsaturations and Ar is aryl, or the corresponding α-silylcarbanion, respectively, with an n-alkanoic acid, formylated in the terminal position, or with its corresponding alkyl ester.
一种用于制备长链饱和或不饱和氧化化合物的过程。所述过程用于制备具有20至36个碳原子的长链饱和或不饱和氧化化合物,选自多廿烷酸、它们的烷基酯、多廿醇及相应具有不饱和烃链的化合物,包括根据Wittig或Peterson烯化反应,与一个末端位置形成甲酰基的n-烷酸或其相应的烷基酯反应的磷叶立德RP(Ar)3的操作,其中R是含有一个或多个乙烯基和/或炔基不饱和的饱和或不饱和烃链,Ar是芳基,或相应的α-硅基负碳离子。
