Paragraph 0047; 0048, (2018/11/27)
The invention belongs to the technical field of organic synthesis and in particular relates to a preparation method for synthesizing high-carbon alkyl acrylate through catalyzing in-situ acid resin. The preparation method comprises the following steps: mixing acrylic acid, the in-situ acid resin, acrylic high-carbon alkyl alcohol, hydroquinone and cyclohexane according to a certain ratio; stirringand heating, and controlling reaction time; after reaction is finished, filtering to remove a resin catalyst; carrying out water washing, neutralization and water washing to obtain the high-carbon alkyl acrylate. According the preparation method provided by the invention, the yield of high-carbon alkyl acrylate can be improved; the in-situ acid resin can be repeatedly utilized, resources are saved and the environment is protected.
