Abstract (en)
[origin: WO2022157370A1] The present invention relates to a continuous method for obtaining 2-ethylhexyl acrylate (2-EHA) from a liquid mixture (1) under an absolute pressure in the range from 0.5 to 100 bar which has a temperature in the range from 0 to 300°C, comprising 2-EHA, at least one high boiler, at least one homogeneous catalyst and at least one low boiler, wherein the mixture (1) is expanded via a pressurizer (3) to an absolute pressure level in the range from 0.1 to 10 bar, the two-phase gas/liquid mixture (16) thereby obtained is continuously supplied to a spiral tube evaporator (4) and there, at a temperature in the range from 50 to 300°C, the 2-EHA content of the liquid phase of the two-phase gas/liquid mixture is reduced by partial evaporation, and the 2-EHA content of the gaseous phase of the two-phase gas/liquid mixture is accordingly increased and both phases are discharged in the form of a resulting two-phase gas/liquid output stream (17).
