It is a structural isomer of 1-propanol and ethyl methyl ether. Its hardener is a peroxide, often MEKP (methyl ethyl ketone peroxide). Chemically, it consists mostly of fatty acid methyl (or ethyl) esters (FAMEs). The reaction between methacrylic acid and methanol results in the ester methyl methacrylate. In chemical analysis, fatty acids are separated by gas chromatography of their methyl ester derivatives. Typical comonomers are vinyl acetate or methyl acrylate. Acetone is used to synthesize methyl methacrylate. Acetic anhydride is mainly produced by the carbonylation of methyl acetate. Hydrolysis of the methyl ester and decarboxylation leads to norfluorocurarine. Solution routes to formaldehyde also entail oxidation of methanol or methyl iodide. Often acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. Chemically, it is the synthetic polymer of methyl methacrylate. Instead of this methyl or phenyl can substitute. Methane can be produced by protonation of methyl lithium and methylmagnesium iodide. Fran is diagnosed with methyl bromide toxicity.
