preparation
1, Acetone is condensed from acetone and barbex and dehydrogenated.
2, Butadiene method in butadiene and acetic acid as raw materials, in the presence of manganese acetate catalyst, in 140 ℃ the condensation pressure, produce gamma - ethylene - gamma butyrolactone. - Butyl ester is an acidic ion exchange resin.
