摘要：
The invention is to a process for producing an acrylate product. The process includes the steps of contacting an alkanoic acid and an alkylenating agent over a catalyst composition under conditions effective to produce the acrylate product. The catalyst composition comprises vanadium, titanium and tungsten. Preferably, the catalyst comprises vanadium to tungsten at a molar ratio of at least 0.02:1, in an active phase.
