    摘要: In one embodiment, the invention is to a process for producing an acrylate product. The process comprises the step of reacting an alcohol and oxygen in a reactor to produce a high temperature alkylenating agent stream comprising an alkylenating agent. The process further comprises the step of contacting an alkanoic acid with at least a portion of the high temperature alkylenating agent stream under conditions effective to form a crude product stream comprising acrylate product and alkylenating agent. The process further comprises the step of separating at least a portion of the crude product stream to form at least one alkylenating agent stream and at least one purified acrylate product stream comprising acrylate product.

    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.

    摘要: In one embodiment, the invention is to a process for producing ethanol. The process comprises the step of hydrogenating an acetic acid feed stream in a first reactor to form a crude ethanol product. The crude ethanol product may comprise, among other components, ethanol, acetaldehyde, and residual acetic acid. The process further comprises the step of recovering acetaldehyde from the crude ethanol product. The process further comprises the steps of feeding a first portion of the recovered acetaldehyde to the first reactor and reacting the first portion of the recovered acetaldehyde in the first reactor to form additional ethanol. In addition, the inventive process may comprise the steps of feeding a second portion of the recovered acetaldehyde to a second reactor and reacting the second portion of the recovered acetaldehyde in the second reactor to form an additional product.
