Pharmacology

Methyl Methacrylate is a methyl ester of methacrylic acid. Methyl methacrylate is a reactive resin, and the polymerized form is used as cement in dentistry, orthopaedic surgery and ophthalmology. The monomer form of this agent has relaxation effect on smooth muscle systemically, which might be a result of nitric oxide-mediated response.

How it is made

Oxidation of tert-butyl alcohol to methacrolein and then to methacrylic acid, followed by reaction with methanol.

Acetone cyanohydrin is treated with concentrated sulfuric acid at 100 °C, affording the corresponding methacrylamide sulfate which is esterified with methanol at 90 °C. After purification, methyl methacrylate (99.8% purity) is obtained in a yield of about 85%.

Ashland Chemical ... has unveiled a new route (to produce methyl methacrylate) based on propylene and carbon monoxide feedstocks.
