Abstract
In one embodiment, the invention relates to a process for producing an acrylate product. The process comprises the step of reacting a reaction mixture comprising an alkanoic acid and an alkylenating agent composition under conditions effective to form a crude acrylate product. The alkylenating agent composition comprises at least 1 wt % of a ring-structured compound comprising at least two oxygen atoms and at least one carbon atom, e.g., trioxane and/or tetraoxane. The process further comprises the step of separating at least a portion of the crude acrylate product to form at least one alkylenating agent stream and at least one purified acrylate product stream comprising acrylate product.
