개요

Dihydro-2(3H)-furanone. An endogenous neuroregulator made from gamma-amino butyrate and the precursor of gamma hydroxybutyrate. It causes selective increase of brain dopamine by inhibiting its release from nerve terminals. The compound has sedative properties at low doses and produces surgical anesthesia at high doses. It is also used as an industrial solvent and precursor.

화학적 성질

γ-Butyrolactone has a faint, sweet, aromatic, slightly buttery odor.

화학적 성질

colourless oily liquid

화학적 성질

Oily, colorless, clear liquid. Faint, pleasant odor.

출처

Reported found as a constituent in coffee aroma; a volatile flavor component in roasted filberts as well. Also reported found in tomato, potato, soybeans, beans, vinegar, mushrooms, roasted chicken, beef, cider, beer, wine, scallops and clams.

용도

r-butyrolactone is one kind of important fine chemicalintermediate, simultaneously also is one kind of performance fine highboiling point solvent, ideal antioxidant, plasticizer,extracting agent, absorbent, dispersing agent, solid stain, Coagulation Reagent.

용도

Intermediate in the synthesis of polyvinylpyrrolidone, DL-methionine, piperidine, phenylbutyric acid, thiobutyric acids. Solvent for polyacrylonitrile, cellulose acetate, methyl methacrylate polymers, polystyrene. Constituent of paint removers, textile aids, drilling oils.

정의

ChEBI: A butan-4-olide that is tetrahydrofuran substituted by an oxo group at position 2.

제조 방법

Detection: 20 to 50 ppm

Taste threshold values

Taste characteristic at 75 ppm: milky, creamy with fruity peach-like afternotes.

일반 설명

Clear colorless oily liquid with a pleasant odor.

공기와 물의 반응

Hygroscopic. Soluble in water.

반응 프로필

gamma-Butyrolactone can react with oxidizing materials, inorganic acids and bases, alcohols and amines. Rapidly hydrolyzed by bases and slowly hydrolyzed by acids. gamma-Butyrolactone is volatile with steam. . The combination of the lactone, butanol, 2,4-dichlorophenol, and sodium hydroxide in the attempted synthesis of 2,4-dichlorophenoxybutyric acid caused a thermal runaway reaction that eventually exploded, [CISHC Chem. Safety Summ., 1977, 48, 3].

위험도

Toxic by ingestion. Questionable carcino- gen.

화재위험

gamma-Butyrolactone is combustible.

Safety Profile

Moderately toxic by ingestion, intravenous, and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data by skin contact. Mutation data reported. Less acutely toxic than ppropiolactone. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, alcohol foam, CO2, dry chemical. Potentially explosive reaction with butanol + 2,4 dichlorophenol + sodium hydroxide. When heated to decomposition it emits acrid and irritating fumes.

잠재적 노출

Used as a chemical intermediate for making other chemicals, including pesticides, cosmetics, and pharmaceuticals; as a solvent for paint, nail polish removers, and industrial chemicals. Used in electronics, drilling and petroleum industries as a stabilizer and solvent. Used as a flavoring agent in various foods and beverages, including grains and breakfast foods, candy, and alcoholic and nonalcoholic drinks. Drug of abuse: the United States Food and Drug Administration has warned the public not to purchase or consume products, containing gamma-butyrolactone (GBL). FDA has also asked the companies that manufacture these products to voluntarily recall them. The agency has received reports of serious health problems—some that are potentially life-threatening—associated with the use of these products. Although labeled as dietary supplements and marketed under various brand names, these products are illegally marketed unapproved new drugs. False advertising claims include building muscles, improved physical performance, enhanced sex, reduced stress and induced sleep

운송 방법

Listed by some sources as unregulated. UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required.

Purification Methods

Dry the lactone over anhydrous CaSO4, then fractionally distil it. Handle it in a fume cupboard due to its TOXICITY. [Beilstein 17 V 7.]

비 호환성

4-Butyrolactone is incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, alcohols, amines, strong and inorganic acids, strong bases. Rapidly hydrolyzed by bases and slowly hydrolyzed by acids. It is hygroscopic and volatile with steam. Combustible; vapor may form explosive mixture with air.

폐기물 처리

Use a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. It is inappropriate and possibly dangerous to the environment to dispose of expired or waste drugs and pharmaceuticals by flushing them down the toilet or discarding them to the trash. Household quantities of expired or waste pharmaceuticals may be mixed with wet cat litter or coffee grounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If possible return the pharmaceutical to the manufacturer for proper disposal being careful to properly label and securely package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator. All federal, state, and local environmental regulations must be observed.
