How is GBL produced?
GBL can be synthesized from gamma-hydroxybutyric acid (GHB) by removal of water or by distillation from such a mixture. It may also be obtained via oxidation of tetrahydrofuran (THF).
What is the boiling point of GBL?
204 °C
gamma-Butyrolactone/Boiling point
Is GBL illegal?
In the US, it is illegal to manufacture or sell GBL or the related products GHB and butanediol (BD). Use of GBL, or the closely related gamma hydroxybutyrate (GHB) and butanediol (BD), has been linked to deaths and cases of serious side effects.
Can you buy GBL?
Just one teaspoon of the party drug GBL can be fatal but a legal loophole means it can be bought on the internet by the litre. Nicknamed Coma in a Bottle, it is illegal to take as a stimulant but can be imported from Europe for its intended use as an industrial cleaner.
Is GBL legal in China?
GBL (and its like chemical 1,4-Butanediol (1,4-BD)) will be illegal by the end of year as Class C drugs under the 1971 Act (subject to Parliamentary approval) with possession and supply limited where they are intended for human consumption.
Which is gamma butyrolactone?
γ-Butyrolactone (GBL) is a hygroscopic colorless, water-miscible liquid with a weak characteristic odor. It is the simplest 4-carbon lactone. It is mainly used as an intermediate in the production of other chemicals, e.g. methyl-2-pyrrolidone.
Can you buy gamma butyrolactone?
You can order gamma-Butyrolactone (GBL) online as a wheel cleaner, paint cleaner and you can also order gamma-Butyrolactone (GBL) for industrial use.
Is GBL cheaper than GHB?
Conclusion: GBL currently represents a growing public health issue since the substance is relatively cheaper and easier to obtain than GHB.
What is the PH of gamma butyrolactone?
At basic pH levels, especially around 12.0, an almost complete conversion of GBL to GHB happens within minutes. At the pH levels of 4.0 to 7.0, the conversion process takes several months….1 x 10-3 to 1 x 10-4 M GBL at 205 nm.

Can you buy GBL in UK?
GBL turns into GHB, the almost identical drug, when consumed. It remains legal to sell GBL as a cleaning product or for industrial use, but since 2009 it has been illegal in the UK to sell, supply, import, export, or produce GBL if “knowing or believing that it will be used for the purpose of human ingestion”.
