General description
Dimethyl succinate (DBE-4 dibasic ester ) is obtained by the oxidation of 1,4-butanediol and butyrolactone by using supported gold, palladium and gold-palladium nanoparticles.
DBE-4 can be used as an intermediate in the preparation of 1,4-butanediol, γ-butyrolactone, tetrahydrofuran and itaconic acid.

The oxidation of 1,4-butanediol and butyrolactone have been investigated by using supported gold, palladium and gold-palladium nanoparticles. The products of such reactions are valuable chemical intermediates and, for example, can present a viable pathway for the sustainable production of polymers.
