2.Product Description:

Butyrolactone (γ-butyrolactone or ) is a hygroscopic colorless liquid with a weak characteristic odor which is soluble in water.  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, and it is used as a recreational intoxicant with effects similar to alcohol.

Butyrolactone has been found in extracts from samples of unadulterated wines.[3] This finding indicates that Butyrolactone 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. Butyrolactone can be found in cheese flavourings but typically results in a content of 0.0002% Butyrolactone in the final foodstuff.

Under acidic conditions it forms an equilibrium mixture of both compounds. These compounds then may go on to form a polymer. When treated with a non-nucleophilic base, like lithium diisopropylamide, Butyrolactone can become an alpha-carbon nucleophile. The related compound caprolactone can be used to make a polyester in this manner.Butyrolactone is not active in its own right; its mechanism of action stems from its identity as a prodrug of .The hypnotic effect of  is enhanced by combination with alcohol. A 2003 rat study showed that Butyrolactone in combination with ethanol showed a potentiated hypnotic effect, as the sleep-timing measure was longer than both of the individual components combined

Butyrolactone is rapidly converted into  by paraoxonase (lactonase) enzymes, found in the blood.[7][8] Animals which lack these enzymes exhibit no effect from Butyrolactone.[7] Butyrolactone is more lipophilic (fat soluble) than, and so is absorbed faster and has higher bioavailability. Because of these pharmacokinetic differences, Butyrolactone tends to be more potent and faster-acting than, but has a shorter duration; whereas the related compound 1,4-butanediol (1,4-B) tends to be slightly less potent, slower to take effect but longer-acting than.

Butyrolactone is a non-toxic transparent liquid in the shape of oil. It can be mixed with water and dissolved by ethanol ether, benzene and acetone. It can dissolve many other organic and inorganic compound. Using Butyrolactone is very safe and convenient, because it is a liquid with high boiling, powerful solvency, good electrical and stability properties.Butyrolactone is an important organic synthetic raw material and a fine solvent. It is mainly used as synthetic pyrolidone series products cyclopropylamine acetyl-r-butyrolactone, besides these,Butyrolactone is also used as solvent for agricultural chemicals, polymer, dyestuff and printing. Using butyrolactone as raw material, we can produce aromatic chemicals, medicinal intermediates and rust remover.

Butyrolactoneand B-D-O have many industrial and commercial uses. One significant use of Butyrolactone  is an intermediate in the manufacture of pyrrolidones, which are widely used industrial chemicals. A second significant use of Butyrolactone, because of its strong solvency properties, is in applications such as circuit board cleaning in electronics and high technology industries, and paint stripping. Other applications include the production of herbicides and as a processing aid in the production of pharmaceutical s. B-D-O is used as an intermediate in common industrial and commercial products such as polyether diols, urethane polymers and polyester polymers. Many of the polyester polymers are used as automotive components such as car bumpers. B-D-O is also used as a plasticizer, a carrier solvent in printing inks and a cleaning agent.
