Abstract: The invention relates to a method for preparing 2-octyl (meth)acrylate by reacting 2-octanol with (meth)acrylic acid in the presence of an acidic esterification catalyst, a polymerisation inhibitor and the entrainer cyclohexane, the method comprising the following steps: • providing a reactor unit (24), a reactor (1) with a reactor heating element (30) being located inside the reactor unit (24), • feeding 2-octanol (13), (meth)acrylic acid (14), acidic esterification catalyst (15), cyclohexane (17) and polymerisation inhibitor (31) into the reactor (1), • performing an esterification in the reactor (1) so as to form a liquid reaction mixture, the esterification taking place in the reactor (1) at a sump temperature in the range from 90 to 130°C and at an absolute pressure in the range of 0.5 to 2.0 bar, and a resultant reaction output from the reactor (1) being obtained, the resultant reaction output containing at least 2-octyl (meth)acrylate, 2-octanol, (meth)acrylic acid, acidic esterification catalyst, cyclohexane, esterification water and polymerisation inhibitor, and the esterification water created during the esterification forming, together with the entrainer cyclohexane, a heterogeneous azeotrope, • evaporating the heterogeneous azeotrope from the liquid reaction mixture of the reactor (1), the evaporation being achieved by the reactor heating element (30), and • separating off the gaseous heterogeneous azeotrope from the reactor (1), the gaseous heterogeneous azeotrope being condensed in a condenser (5) and then fed to a phase separator (6), and the esterification water being separated off as lower phase and the cyclohexane being separated off as upper phase in this phase separator (6).
