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.
