Process for Making Acrylic Acid by Integrating Acetic Acid Feed Stream from Carbonylation Process |
摘要 |
In one embodiment, the invention is to a process for producing acrylic acid, comprising the step of providing from a distillation column in a carbonylation process a purified acetic acid stream comprising at least 0.15 wt % water. The process further comprises the step of condensation acetic acid of the purified acetic acid stream and an alkylenating agent in the presence of a catalyst and under conditions effective to form a crude acrylate product comprising acrylic acid and water. Acrylic acid is recovered from the crude acrylate product. |
