An improved process for the manufacture of technical grade (meth)acrylic acid, e.g., acrylic acid, the process comprising producing a hydrated reaction product from the gas-phase oxidation of at least one (meth)acrylic acid precursor, e.g., propylene, followed by first dehydrating and then concentrating the reaction product, the improvement comprising controlling at least one of the water, acetic acid and (meth)acrylic acid content of the reaction product during the purification of the reaction product using on-line, near IR spectroscopy.

Control of a process for the purification of (meth)acrylic acid using on-line, near IR analysis

Technical grade acrylic acid derived from renewable resources utilizing a base catalyst system by a process including reacting lactide (or lactic acid oligomers) with methyl acetate to form methyl 2-acetoxypropionate in the presence of a base catalyst such as sodium methoxide, pyrolyzing the methyl 2-acetoxypropionate, with or without a catalyst, to methyl acrylate and acetic acid, transesterifying the mixture to acrylic acid and methyl acetate, separating and purifying the acrylic acid by distillation late in the presence of polymerization inhibitor(s). The disclosed process will produce a 'green' (i.e. renewable resources derived) acrylic acid and/or methyl acrylate ester.

Acrylic acid and acrylate ester from lactide process

The present application provides a method for producing an beta-lactone product. The method includes the steps of: reacting an epoxide, a solvent with a carbonylation catalyst and carbon monoxide to produce a reaction stream comprising a beta-lactone then separating a portion of the beta-lactone in the reaction stream from the solvent and carbonylation catalyst to produce: i) a beta-lactone stream with the beta-lactone, and ii) a catalyst recycling stream including the carbonylation catalyst and the high boiling solvent; and adding the catalyst recycling stream to the feed stream.

The present invention relates to a polymerization inhibitor composition and a method of inhibiting polymerization of distillable monomers in liquid and evaporated/condensed phases with the polymerization inhibitor composition. The polymerization inhibitor composition is useful for inhibiting polymerization of the distillable monomers during manufacture, purification (e.g., distillation), handling, and storage thereof.

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.

Acrylic acid from lactide and process

Continuous flow systems and methods produce succinic anhydride by a double carbonylation of ethylene oxide with carbon monoxide and at least one catalyst. In some embodiments, the double carbonylation occurs using a single catalyst. In other embodiments, a first catalyst is used to promote the first carbonylation, and a second catalyst different from the first catalyst is used to promote the second carbonylation. The succinic anhydride is isolated from the product stream by crystallization and the catalyst is recycled to the reaction stream.
