Abstract
The invention relates to the production of 2-octyl acrylate of high purity and in good yield, that includes the recycling of economically upgradable products, such as un-reacted reactants and catalyst. The process uses ethyl titanate in solution in 2-octanol or 2-octyl titanate as a tranesterification catalyst and employs a purification train comprising only two distillation columns.
