  • Preparation of methacrylic acid and its esters.
  • To prepare ethyl hydroxy-isobuty rate a pharmaceutical intermediate.
  • For manufacturing of azobisisobutyro-nitrile (AIBN), a very useful catalyst for vinyl polymerization.
  • ACH can be hydrogenerated in methanolic acetate acid in the presence of cobalt or silica gel to give predominantly -B-hydroxy- Isobuty/amine with liquid secondary and tertiary amine by-products.
