    摘要: In one embodiment, the invention is to a process for producing an acrylate product. The process comprises the step of dehydrating a crude alkylenating agent stream to form a dehydrated alkylenating agent stream and a water stream. The process further comprises reacting acetic acid with at least a portion of the dehydrated alkylenating agent stream to form a crude acrylate product stream comprising acrylate product and alkylenating agent stream. The dehydrating of the crude alkylenating stream is accomplished using at least one evaporator or at least one distillation column.
