Abstract
In one embodiment, the invention is to a process for producing an acrylate product. The process comprises the step of reacting an alkanoic acid and an alkylenating agent over a catalyst to produce a crude acrylate product stream, and to product a used catalyst. The used catalyst may then be contacted with a regenerating stream to form a regenerated catalyst. Alkanoic acid and alkylenating agent may then be reacted over the regenerated catalyst to product additional crude acrylate product stream.
