Gamma-Butyrolactone from BDO

Gamma - Butyrolactone from Butanediol dehydrogenation (GBL)




γ-Butyrolactone (GBL) is a hygroscopic colorless, water-miscible liquid used as an intermediate in the production of other chemicals.                                                                                                                                          

GBL is mainly used in the manufacturing of N-Methyl Pyrrolidone (NMP) and 2-Pyrrolidone, which are widely used as industrial chemicals. Thanks to its strong solvency properties, GBL is also used as circuit board cleaning in electronics and paint stripping.


CONSER, having an extensive experience in the branch of Maleic Anhydride derivatives - Butanediol, Tetrahydrofuran, Gamma-Butryrolactone -, developed a process for the production of GBL from Butanediol dehydrogenation. This technology has many benefits, such as: nearly total BDO conversion; very high GBL selectivity; low catalyst consumption; high GBL purity (electronic grade); low utilities consumption.


CONSER is able to provide the technical design also for the co-production of Gamma-Butyrolactone, Butanediol and Tetrahydrofuran from Maleic Anhydride. For additional information on the latter, see ‘Gamma-Butyrolactone’ page.
