Method for the discontinuous production of (meth) acrylates of mixtures of C10 alcohols, by reacting (meth) acrylic acid with an isomeric 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, 2isopropyl-4-methylhexanol, 2-isopropyl-5-methylhexanol and / or 2-propyl-4, 4-dimethylpentanol, in the presence of al less an acid catalyst and at least one polymerization inhibitor and in the presence of a solvent that forms an azeotrope with water, the azeotrope is distilled and concentrated, in which case the condensate is divided into an aqueous and an organic phase, characterized in that a ) the esterification is carried out in a reactor with a recirculation evaporator and b) in the presence of a solvent, and c) because the crude product is then purified by distillation for purification. |
