摘要： The invention relates to a liquid-liquid extraction method, which includes: supplying a main liquid input flow containing at least one compound of interest and a supplementary compound; supplying a washing liquid flow; extracting the supplementary compound from the main liquid input flow by contact with the washing liquid flow, making it possible to collect an main liquid output flow, in which the surplus compound is depleted relative to the main liquid input flow, wherein: the main liquid input flow and the washing liquid flow have a density difference of no more than 50 kg/m3 as well as an interfacial tension of no more than 3 dynes/cm; and the extraction step is carried out in a packed contactor, the weight ratio of the washing liquid flow to the main liquid flow at the input being 0.3 to 0.5. The invention also relates to a method for producing an acrylic ester wherein the process flow is processed by means of the aforementioned liquid-liquid extraction method.

摘要： The present invention relates to a method for continuous preparation of light acrylate, by reaction of a light alcohol with a flow of raw ester-grade acrylic acid including more than 8 wt % of Michael adducts. According to said method, the thermal dissociation of the Michael adducts contained in said flow of raw ester-grade acrylic acid or generated
in situ in the reaction area, and the esterification, with a light alcohol, of the acrylic acid in said flow of raw ester-grade acrylic acid and/or generated
in situ by said thermal dissociation are carried out simultaneously in a single reaction area, the effluent coming out of the reaction area then being subjected to a treatment and purification line resulting in the production of a purified light acrylate, and the reaction residue remaining fluid enough to be drawn off by means of a pump.

摘要： 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.

摘要： The subject matter of the present invention is an improvement in the continuous production of methyl (meth)acrylate or of ethyl (meth)acrylate by direct esterification of (meth)acrylic acid with methanol or ethanol, under reaction conditions for which the acid is in excess relative to the alcohol, in particular with an acid/alcohol molar ratio of between 1.0 and 4, and under a pressure ranging from atmospheric pressure to 5 bar. The process of the invention makes it possible to minimize the formation of ethyl ethoxypropionate during the esterification reaction, and results in an improvement in the material balance, simplification of the purification train for the desired ester, and optimization of the energy balance.
