Buy GBL Online – Gamma-butyrolactone, y-butyrolactone, GBL
Buy GBL Online at GBLMagic.
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.
In humans, GBL acts as a prodrug for γ-hydroxybutyric acid (GHB), and it is used as a recreational CNS depressant with effects similar to barbiturates. Also check γ-Butyrolactone (GBL) Buy GBL Online.
GBL has been found in extracts from samples of unadulterated wines.
This finding indicates that GBL is a naturally occurring component in some wines and may be present in similar products.
The concentration detected was approximately 5 μg/mL and was easily observed using a simple extraction technique followed by GC/MS analysis.
GBL can be found in cheese flavorings but typically results in a content of 0.0002% GBL in the final foodstuff.
Production and synthesis
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 using the Sandmeyer reaction.
Butyrolactone is principally a precursor to other chemicals. Reaction with methylamine gives NMP. Ammonia gives pyrrolidone.
It is also used as a solvent in lotions and some polymers. Butyrolactone, with its wide liquid range, chemical stability, and high dielectric constant,
is used in some batteries but primarily is found in electrolytic capacitors as the organic solvent. In this capacity, it is frequently mixed with a small ratio of ethylene glycol, “9:1” being common, to vary internal resistivity.
Recently buy GBL online has become an important solvent for the development of organic perovskites (such as Methylammonium lead halide), novel solar cell materials that can be processed from solution.
What is gamma-Butyrolactone (GBL)
Gamma-Butyrolactone (γ-butyrolactone or GBL) is a hydroscopic colorless liquid with a weak characteristic odor which is soluble in water.
GBL is a common solvent and reagent in chemistry as well as being used as a flavouring, as a cleaning solvent, as a superglue remover, and as a solvent in some wet aluminium electrolytic capacitors.
In humans it acts as a prodrug for GHB, and it is used as a recreational intoxicant with effects similar to alcohol. Buy GBL Online.
GBL is a good solvent for the precursor salts such as lead halides and methylammonium iodide or formamidinium iodide. Often mixtures of GBL and DMSO yield the best results.
GBL is an alternative to the more toxic solvent dimethylformamide that was used in the earlier stages of the development of the perovskite solar cell.
