Abstract
Technical grade acrylic acid derived from renewable resources utilizing a homogeneous nickel catalyst system by a process including reacting lactide with acetic acid to form 2-acetoxypropionic acid in the presence of a homogeneous nickel catalyst, pyrolyzing, with or without a catalyst, the 2-acetoxypropionic acid to acrylic acid and acetic acid, condensing and collecting the pyrolysis products in the presence of polymerization inhibitor(s) and purifying the acrylic acid by distillation in the presence of polymerization inhibitor(s). Acrylic acid and methyl acrylate are produced from methyl 2-acetoxypropionate which comes from fermentation derived lactic acid. The disclosed process will produce a 'green' (i.e. renewable resources derived) acrylic acid and methyl acrylate ester.
