    • The present invention relates to a process for preparing 3-alkoxypropan-1-ols of the general formula I by catalytic hydrogenation of esters of the general formula II, where the radicals R1 and R2 and R3, R4 and R5 are each, independently of one another, a straight-chain or branched C1-C20-alkyl radical which may optionally be substituted by one or more C1-C20-alkoxy radicals or interrupted by one or more oxygen atoms in the chain, C6-C20-aryl, C7-C20-arylalkyl which may optionally be substituted by one or more C1-C20-alkoxy radicals or interrupted by one or more oxygen atoms in the alkyl chain, C7-C20-alkylaryl which may optionally be substituted by one or more C1-C20-alkoxy radicals or interrupted by one or more oxygen atoms in the alkyl chain, a C1-C20-cycloalkyl radical which may optionally be substituted by one or more C1-C20-alkoxy radicals and R2, R3 and R4 can, independently of one another, also be hydrogen, over chromium- and nickel-free catalysts.
    • 本发明涉及一种制备通式Ⅰ的3-烷氧基丙-1-烯的方法,其中通式Ⅱ的酯通过催化氢化,其中基团R 1和R 2以及R 3,R 4和R 5各自独立地为 另一个直链或支链的C 1 -C 20 - 烷基,其可任选地被一个或多个C 1 -C 20烷氧基取代或被链中的一个或多个氧原子间隔,C 6 -C 20芳基,C 7 -C 20 可以任选地被一个或多个C 1 -C 20烷氧基取代或被烷基链中的一个或多个氧原子间隔的芳基烷基,可任选被一个或多个C 1 -C 20烷氧基取代的C 7 -C 20烷基芳基 或被烷基链中的一个或多个氧原子中断,可任意被一个或多个C 1 -C 20烷氧基取代的C 1 -C 20环烷基,R 2,R 3和R 4可彼此独立地为 氢,超过无铬和无镍的催化剂。
