    Abstract: Process for preparing (meth)acrylates of C10-alcohol mixtures, by reacting (meth)acrylic acid with an isomer mixture of C10-alcohols composed of 2-propylheptanol as the main isomer and at least one of the C10-alcohols 2-propyl-4-methylhexanol, 2-propyl-5-methylhexanol, 2-isopropylheptanol, 2-isopropyl-4-methylhexanol, 2-isopropyl-5-methylhexanol and/or 2-propyl-4,4-dimethylpentanol, in the presence of at least one acidic catalyst and of at least one polymerization inhibitor and in the presence of a solvent which forms an azeotrope with water, the azeotrope is distilled off and condensed, and the condensate splits into an aqueous phase and an organic phase, wherein a) the esterification is performed in a reactor with a circulation evaporator and b) in the presence of a solvent, and c) the crude product is purified by subsequent purifying distillation.

    Abstract translation: 通过使（甲基）丙烯酸与由2-丙基庚醇组成的C 10醇的异构体混合物作为主要异构体和至少一种C10-醇2-丙基 - 丙烯酸的至少一种来制备C10-醇混合物的（甲基）丙烯酸酯的方法， 4-甲基己醇，2-丙基-5-甲基己醇，2-异丙基庚醇，2-异丙基-4-甲基己醇，2-异丙基-5-甲基己醇和/或2-丙基-4,4-二甲基戊醇，在至少 一种酸性催化剂和至少一种聚合抑制剂，并且在与水形成共沸物的溶剂的存在下，蒸馏出共沸物并冷凝，并且冷凝物分解成水相和有机相，其中a）酯化 在具有循环蒸发器的反应器中进行，和b）在溶剂存在下进行，和c）通过随后的纯化蒸馏纯化粗产物。
