Process Designs for Converting Propylene Glycol to Acrylic

oxidation of propylene glycol to lactic acid and high temperature dehydration to acrylic acid or by (2) high temperature dehydration of propylene glycol to allyl alcohol and further high temperature oxidation to acrylic acid Liquid− liquid extraction was found to be a key operation in both production processes At similar overall yields the allyl alcohol route appears inherently favored
