Abstract:
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, bismuth and titanium. Preferably, the catalyst comprises 0.3 wt % to 30 wt % vanadium, 0.1 wt % to 69 wt % bismuth and 0.1 wt % to 61 wt % tungsten, in an active phase.
