    Abstract: Butyl acrylate is prepared by reacting acrylic acid and butanol in a reactor in the presence of an esterification catalyst the water formed being entrained by distillation in a column (2) in the form of a heteroazeotropic mixture with butanol mixture following condensation, being separated in a decanter (3) to give an upper, organic phase which is recycled to the top of the distillation column (2) and a lower, aqueous phase which is drawn off. The reaction is conducted with deferred introduction of part of the butanol at the top of the distillation column (2) or to the decanter (3) or to the reactor (1), the butanol/acrylic acid molar ratio being initially between 0.5 and 1 before rising to between 1 and 1.5 following the completion of the deferred introduction of the butanol.

    Abstract: 2-Ethylhexyl acrylate is manufactured according to a process for the direct esterification of acrylic acid with 2-ethylhexanol catalysed by sulphuric acid, the acrylic acid subjected to the esterification being stabilized by at least one stabilizing agent, the said esterification being followed by the neutralization by a base of the crude reaction mixture (B1) obtained, the resulting salts passing into the aqueous phase (A1) of the said mixture, the organic phase (O1) and the aqueous phase (A1) resulting from this neutralization being separated and the 2-ethylhexyl acrylate being recovered from the organic phase (O1). To suppress the emulsions which appear during the said neutralization, the stabilizer or stabilizers of acrylic acid is/are chosen with the exclusion of hydroquinone, in the absence of which the aqueous phase of the process is stabilized before and/or during the neutralization.
