Description

Methacrylic acid is is a colorless, moderately volatile, corrosive liquid with a strongly acrid odor. It was first prepared in 1865 from ethyl methacrylate, in turn obtained by dehydration of ethyl α-hydroxyisobutyrate. It is used as a monomer to prepare polymers. It acts a precursor for the preparation methyl methacrylate, N-substituted methacryl amides, methacrylamide, N-substituted methacryl amides and acryloyl chloride.
