Abstract: This invention relates to a process for the continuous production of a (meth)acrylic ester by transesterification reaction between a C1-C4 light alkyl (meth)acrylate, with a heavy alcohol in the presence of a catalyst, characterised in that the flows feeding the reactor are introduced through a static mixer placed on a recirculation loop of the reactor. The use of a static mixer improves the selectivity of the reaction and consequently the overall productivity of (meth)acrylic ester synthesis process.

Abstract: The invention relates to the production of alkyl acrylate according to a continuous transesterification process. In one embodiment the process of the invention uses a simple column to purify a reaction mixture of acryl acrylate in one step yielding alkyl acrylate with a purity of greater than 99.8%.

Abstract: The invention relates to the industrial production of highly pure 2-propylheptyl acrylate with a high yield according to a process by transesterification, preferably in semi-continuous mode. The process according to the invention uses ethyl titanate in solution in 2-propylheptanol or 2-propylheptyl titanate as transesterification catalyst, and implements a purification sequence comprising a single distillation column and a film evaporator.

Abstract: The invention relates to a process for continuously producing 2-octyl acrylate by reacting acrylic acid and 2-octanol in the presence of a sulfonic acid esterification catalyst and at least one polymerization inhibitor. The water formed by the esterification reaction is entrained by distillation in a column surmounting the reactor in the form of a heteroazeotropic mixture with the 2-octanol which is then subjected, after condensation, to separation in a decanter so as to give an upper organic phase and a lower aqueous phase. The reaction mixture containing the reaction product and residual by-products are purified by separation means in order to obtain: (1) pure 2-octyl acrylate and (2) unreacted 2-octanol and acrylic acid compounds that will be recycled along with the catalyst.

Abstract: The invention relates to the production of 2-octyl acrylate of high purity and in good yield, that includes the recycling of economically upgradable products, such as un-reacted reactants and catalyst. The process uses ethyl titanate in solution in 2-octanol or 2-octyl titanate as a tranesterification catalyst and employs a purification train comprising only two distillation columns.

Abstract: The invention relates to a method for producing N,N-dimethylaminoethyl acrylate by the transesterification reaction of an alykl acrylate by N1N-dimethylaminoethanol, and more particularly relates to a method for purifying the azeotropic fraction generated during said reaction, thereby enabling the recycling thereof on the alkyl acrylate production unit. The aim of the method of the invention is in particular to remove the acetaldehyde and the dialkoxyethane contained in the azeotropic fraction, either by the direct distillation of the azeotropic fraction or by the distillation of the aqueous phase resulting from the water scrubbing of the azeotropic fraction.
