Production
In the most common route, methacrylic acid is prepared from acetone cyanohydrin, which is converted to methacrylamide sulfate using sulfuric acid. This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step. In the second route, isobutylene or tert-butanol are oxidized to methacrolein, then methacrylic acid. Methacrolein for this purpose can also be obtained from formaldehyde and ethylene. Isobutyric acid can also be dehydrogenated to methacrylic acid.
MAA (Methacrylic Acid) can also be prepared by decarboxylation of itaconic acid, citraconic acid, and mesaconic acid. Such green precursors are not of commercial value.
MAA (Methacrylic Acid) is, however, obtained by boiling citra- or meso-brompyrotartaric acids with alkalis.
