How to make gbl?
γ-Butyrolactone is produced industrially by dehydrogenation of 1,4-butanediol at a temperature of 180–300 °C and atmospheric pressure in the presence of a copper catalyst.
The yield of this process is approximately 95%. The purification takes place with a liquid-gas-phase extraction.
In the laboratory, it may also be obtained via the oxidation of tetrahydrofuran (THF), for example with aqueous sodium bromate. An alternative route proceeds from GABA via a diazonium intermediate.
A milliliter of pure GBL metabolizes to the equivalent 1.65 g of NaGHB, the common form, so doses are measured in the single milliliter range, either taken all at once or sipped over the course of a night.
ghb vs gbl：
What is it?
- G is the name given to the drugs GHB (gamma hydroxybutyrate) and GBL (gamma butyrolactone).
- Other names include G, Gina, Liquid E and Liquid ecstasy.
- GHB is an odourless, oily liquid, with a slightly salty taste, usually sold in small bottles or capsules. The effects usually occur within 15-20 minutes and last up to 3-4 hours.
- GBL is a liquid with a chemical smell and taste. GBL is a precursor to GHB, which means that it is converted to GHB inside your body after swallowing. It has a faster onset of action than GHB, and is often more potent – so a smaller dose is required to have the same effect.
- G is usually swallowed in its liquid form, often mixed with water or a soft drink. Never mix G with alcohol as these 2 substances interact and can lead to death. Less often it is snorted or inhaled. Injecting G is dangerous.
What does it do?
- Both GHB and GBL are depressant drugs which can produce a high with small doses, and cause sedation with only slightly higher doses. People report that G makes them feel euphoric, with a loss of inhibitions, increased confidence, and a higher sex drive.
What are the risks?
- It is easy to overdose on G, as there is not much difference (less than one millilitre) between a dose that gets a person high, and a dose that has them “going under” – becoming unconscious and unresponsive.
- Avoid mixing G with alcohol. This can increase the risk of going under, and delay the time it takes for G to take effect – interfering with safe dosing intervals.
- A number of deaths have been caused by G. Death can result from overdose, or severe withdrawal syndrome.
- Using G with other depressant drugs, such as alcohol, benzodiazepines and ketamine can increase the risk of going under and stopping breathing. In some cases, people might be hospitalised after using G.
- G is addictive and dependence can develop quickly. Dependence mean people will develop withdrawal symptoms on stopping use, which can be severe and life-threatening.
- The sedative properties of G can leave a person incoherent or comatose. People around you may take advantage of this to have sex with you without your consent.
