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.
