Patent ID: 8318970

Claim:
A process for batchwise preparing (meth)acrylates of C 10 -alcohol mixtures, comprising: reacting (meth)acrylic acid with an isomer mixture of C 10 -alcohols composed of 2-propylheptanol as the main isomer and at least one of the C 10 -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 selected from the group consisting of a mineral acid and a sulfonic acid and of at least one polymerization inhibitor and in the presence of at least one solvent selected from the group consisting of an aliphatic hydrocarbon, a cycloaliphatic hydrocarbon, and an aromatic hydrocarbon, which forms an azeotrope with water, the azeotrope is distilled off and condensed during the reacting, and the condensate splits into an aqueous phase and an organic phase to obtain a crude product, wherein the reaction is performed in a reactor with a circulation evaporator, wherein the organic phase is not returned to the reactor during the reacting, and wherein the crude product is purified by distillation via at least one of a rectification column and a thin-film evaporator.
