  There is provided a method for handling high-viscosity substances discharged from a production process of acrylic acid or esters thereof by gas-phase catalytic oxidation, which method is improved such that upon transporting the high-viscosity substances in a molten state to a storage tank through a pipeline, the retention or clogging of the high-viscosity substances in the pipeline can be effectively prevented without adding a solvent thereto, resulting in smooth transportation thereof through the pipeline. In the method for handling high-viscosity substances discharged from a production process of acrylic acid or esters thereof by gas-phase catalytic oxidation according to the present invention, when the high-viscosity substances are transported to a storage tank through a pipeline, contents of acrylic acid polymers and a polymerization inhibitor in the high-viscosity substances are controlled to not less than 40% by weight and not less than 4% by weight, respectively, and the high-viscosity substances are maintained at a temperature of not less than 110° C.

  A process is disclosed for the production of 2-ethylhexyl acrylate which includes a method of recycling unreacted 2-ethylhexyl alcohol. A liquid side stream draw containing about or greater than 65% alcohol, is taken from the top one third of the light ends recovery tower. By employing a side stream, 2-ethylhexyl alcohol can be recovered and directly recycled to the 2-ethylhexyl acrylate reactor thereby increasing raw material efficiency and avoiding problematic emulsion issues associated with use of other in-process streams.

  The present invention relates to a method for producing a C 4 -C 10 alkyl (meth)acrylate, by direct esterification of (meth)acrylic acid by the corresponding alcohol, the reaction water being removed in the form of an azeotrope with the esterification alcohol from a distillation column mounted over the esterification reactor comprising a cationic resin as a catalyst. Said method is characterized in that the molar ratio of alcohol to acid at the inlet of the reactor is between 1.4 and 3, and in that the crude reaction mixture circulates in a recirculation loop joining the reactor and the water removal column, at a recirculation rate of between 6 and 25, expressed by the mass ratio between the flow fed into the loop and the flow sent to a purification treatment.
