Abstract: Disclosed is a method for producing (meth)acrylates of C
10 alcohol mixtures by reacting (meth)acrylic acid with an isomer mixture of C
10 alcohols comprising 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 acid catalyst and at least one polymerization inhibitor and in the presence of a solvent forming an azeotrope along with water, removing the azeotrope by distillation and condensing the same such that the condensate is decomposed into an aqueous and an organic phase. According to said method, a) the esterification process is carried out in a reactor comprising a circulating evaporator, b) in the presence of a solvent, and c) the raw product is purified in a subsequent pure distillation process.
