Procedure
Finally, several other processes have become known (Stanford Research Institute Report, 11: 30) for oxidizing isobutene with nitric acid or a mixture of nitric acid and nitrogen dioxide, or mixtures thereof with acetic acid, to obtain α-hydroxyisobutyric acid, a precursor of methacrylic acid. By splitting off water, methacrylic acid is obtained from α-hydroxyisobutyric acid (German Pat. No. 1,568,948=British Pat. No. 1,080,473 and Canadian Pat. No. 771,714; DOS No. 1,768,253=British Pat. No. 1,179,987).
