Catalyst for producing acrylic acids and acrylates |
| 摘要 |
In one embodiment, 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 a metal phosphate matrix containing vanadium and bismuth. Preferably, the catalyst comprises, in an active phase, vanadium to bismuth at a molar ratio of at least 0.02:1. Preferably, the catalyst composition is substantially free of titanium. |
