Gamma-butyrolactone is a chemical used for both medical and industrial purposes. It is a clear, oily liquid with a pleasant, faintly sweet odor. Do not confuse GBL with gamma-hydroxybutyrate (GHB).
Though GBL does have some medical uses, its acutely toxic properties make it safer and more effective as a solvent. Due to its corrosive nature, you should always take great care when handling GBL.
For industrial use, the production of GBL begins with the dehydrogenation of 1,4 Butanediol, a form of primary alcohol often found in paint thinners. Dehydrogenation happens at a temperature of 180-300 degrees Celsius. Atmospheric pressure and a copper catalyst are also essential for this process.
Other names for Gamma-butyrolactone besides GBL include:
Dihydrofuran-2(3H)-one
Butyrolactone
1,4-Lactone
4-Butyrolactone
4-Hydroxybutyric acid lactone
gamma-Hydroxybutyric acid lactone
