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.
