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
