| titleOfInvention | Process for producing alkylene glycol di (meth) acrylate |
| abstract | PROBLEM TO BE SOLVED: To recover an organotin compound catalyst in a process for producing an alkylene glycol di (meth) acrylate by transesterifying an alkyl (meth) acrylate and a hydroxyalkyl (meth) acrylate in the presence of the organotin compound catalyst. It can be used repeatedly for transesterification with good reproducibility. [Solution] The reaction mixture after the transesterification reaction is distilled to separate the target product, such as alkylene glycol di (meth) acrylate, and the distillation residue containing the catalyst component is cooled to 100 ° C. or lower, and the generated precipitate is removed. Add the hydroxyalkyl (meth) acrylate to the distillation residue, dissolve it, circulate and reuse it in a new transesterification reaction. [Selection] Figure 1 |
