Methyl+methacrylate

This is an organic compound. It is also a monomer with the formula is CH2=C(CH3)COOCH3. It is a colorless liquid and a the methyl ester of methacrylic acid (MAA) =Uses:= It is used in plastics, acrylics, 2 part adhesives for countertops, "cement" in bone surgeries, dental and orthodontic procedures.

=How it is made:= The compound is made by different processes. The main is by [|acetone cyanohydrin] (ACH), using [|acetone] and [|hydrogen cyanide]. Cyanohydrin is converted with sulfuric acid to a sulfate ester of the methacrylamide ( [|methanolysis] ), which gives [|ammonium bisulfate] and MMA. This produces large amounts of [|ammonium sulfate]. A second way is to start with an [|isobutylene] which is oxidized first to [|methacrolein] and then to methacrylic acid. MMA can also be prepared from methyl propionate and [|formaldehyde]. [|[2]]
