    • A process for the hydrogenation of a reactant selected from: (a) a 5- or 6-membered lactone that is substituted at the ring-closing carbon atom and has a proton at a carbon atom adjacent to the ring-closing carbon atom; (b) an ester of a carboxylic acid having a gamma-carbonyl group and a proton at a carbon atom adjacent to the carbon atom of the carbonyl group; and (c) a carboxylic acid having a gamma-carbonyl group and a proton at a carbon atom adjacent to the carbon atom of the carbonyl group, which process involves contacting the reactant with a catalyst in the presence of hydrogen, at a temperature from 100 to 350° C. and a pressure from 1 to 150 bar (absolute), provided the pressure is low enough to avoid condensation of the heaviest feed component at the temperature chosen, and wherein the catalyst is a weakly acidic heterogeneous catalyst comprising a hydrogenating metal.
    • 一种选自以下的反应物的氢化方法:(a)在闭环碳原子上被取代并在与闭环碳原子相邻的碳原子处具有质子的5或6元内酯; (b)在与羰基的碳原子相邻的碳原子处具有γ-羰基和质子的羧酸的酯; 和(c)在与羰基碳原子相邻的碳原子处具有γ-羰基和质子的羧酸,该方法包括在氢气存在下使反应物与催化剂接触,温度为100℃ 至350℃,压力为1至150巴(绝对值),条件是压力足够低以避免在所选择的温度下最重的进料组分冷凝,并且其中催化剂是弱酸性非均相催化剂,其包含氢化金属 。

    • A process for the catalytic conversion of carboxylic acids with acetylene to vinylesters. At least one, preferably saturated, secondary carboxylic ester and/or at least one, preferably tertiary carboxylic acid is (are) passed in the gas phase together with acetylene at an elevated temperature, preferably in the range of from 150 to 400° C., over a catalyst comprising zinc and a solid inert oxidic carrier, preferably alumina. The carboxylic acids have advantageously the following formula: in which R1 is H or an alkyl group and R2 and R3 are alkyl groups, the total number of C-atoms of R1+R2+R3 being in the range of from 3 to 18. These vinylesters have a good stability and are particularly useful components in emulsion paints and as modifiers in alkyd and epoxy resin.
    • 将羧酸与乙炔催化转化成乙烯基酯的方法。在高温下,将至少一种优选饱和的仲羧酸酯和/或至少一种优选叔羧酸与乙炔一起通入气相中 温度,优选在150-400℃的范围内,在包含锌和固体惰性氧化载体的催化剂,优选氧化铝中。羧酸有利地具有下式:其中R 1是H或烷基,R 2 并且R 3是烷基,R 1 + R 2 + R 3的C原子总数在3至18的范围内。这些乙烯基酯具有良好的稳定性,并且在乳液漆中和作为醇酸树脂和环氧树脂中的改性剂是特别有用的组分 树脂。
