Description:
 
 

1,4-Butanediol is classified as a subclass of alcoholic compounds called diols. Diols are named for having two alcohol (OH-) substitutions in their structure. 1,4-Butanediol is comprised of a butane chain of four carbon groups with an alcohol grou


1,4-Butanediol (1,4-B, butylene glycol, or BD) is a thick, colourless liquid which is nearly odorless with a distinct bitter taste. 1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1,4-butanediol is used for the synthesis of γ-butyrolactone (GBL).


In humans, it acts as a depressant and a prodrug for GHB where 1ml is equivalent to 1g of GHB. It is used as a recreational intoxicant with effects similar to alcohol
1,4-Butanediol, as well as GBL, will dissolve most types of plastic over time.For this reason, it is recommended to only transport and store the drug using a glass container, standard gelatin capsules (not vegetarian), or high-density polyethylene plastic (also known as #2 recycled plastic). To check the type of plastic used on a bottle, one can look at the bottom for a number in the triangle shaped recycling label.

1,4-Butanediol Usage And Synthesis
Chemical Properties 1,4-butanediol (1,4-BD) is a colorless, viscous liquid derived from butane by placement of alcohol groups at each end of its molecular chain and is one of four stable isomers of butanediol.the hydroxyl function of each end group of the Butanediol reacts with different mono- and bifunctional reagents: for example with dicarboxylic acids to polyesters, with diisocyanates to polyurethanes, or with phosgene to polycarbonates. 1.4-Butanediol (BDO) is a high-quality intermediate. BDO and its derivatives are widely used for producing plastics, solvents, electronic chemicals and elastic fibers. Additionally BDO is also a building block for the synthesis of polyesterpolyols and polyetherpolyols. BASF is the most significant producer of 1,4-Butanediol and its derivatives worldwide.
Uses

00001. Butanediol and its derivatives is used in a broad spectrum of applications in the chemical industry; amongst others in the manufacturing of technical plastics, polyurethanes, solvents, electronic chemicals and elastic fibres.

00002. 1,4-Butanediol is used in the synthesis of epothilones, a new class of cancer drugs. Also used in the stereoselective synthesis of (-)-Brevisamide.

00003. 1,4-Butanediol's largest use is within tetrahydrofuran (THF) production, used to make polytetramethylene ether glycol, which goes mainly into spandex fibers, urethane elastomers, and copolyester ethers.

00004. It is commonly used as a solvent in the chemical industry to manufacture gamma-butyrolactone and elastic fibers like spandex.

00005. It is used as a cross-linking agent for thermoplastic urethanes, polyester plasticizers, paints and coatings.

00006. It undergoes dehydration in the presence of phosphoric acid yielded teterahydrofuran, which is an important solvent used for various applications.

00007. It acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU).

00008. It finds application as an industrial cleaner and a glue remover.

00009. 1,4-butanediol is also used as a plasticiser (e.g. in polyesters and cellulosics), as a carrier solvent in printing ink, a cleaning agent, an adhesive (in leather, plastics, polyester laminates and polyurethane footwear), in agricultural and veterinary chemicals and in coatings (in paints, varnishes and films).

Uses butylene glycol is a solvent with good antimicrobial action. It enhances the preservative activity of parabens. Butylene glycol also serves as a humectant and viscosity controller, and to mask odor.
Uses 1,4-Butanediol is used to produce polybutyleneterephthalate, a thermoplastic polyester;and in making tetrahydrofuran, butyrolactones,and polymeric plasticizers.
Production Methods Methods of manufacturing:
The most prevalent 1,4-BD production route worldwide is BASF's Reppe process, which reacts acetylene and formaldehyde. Acetylene reacts with two equivalents of formaldehyde to form 1,4-butynediol, also known as but-2-yne- 1,4-diol. Hydrogenation of 1,4-butynediol gives 1,4-butanediol. 1,4-BD is also made on a large industrial scale by continuous hydrogenation of the 2-butyne- 1,4-diol over modified nickel catalysts. The one-stage flow process is carried out at 80 - 160 deg C and 300 bar.
Mitsubishi uses a three-step process:
(1) the catalytic reaction of butadiene and acetic acid yields 1,4-diacetoxy-2-butene;
(2) subsequent hydrogenation gives 1,4-diacetoxybutane; and
(3) hydrolysis leads to 1,4-butanediol.
General Description Odorless colorless liquid or solid (depending upon temperature).
Air & Water Reactions Highly flammable. 1,4-Butanediol is hygroscopic. Water soluble.
Reactivity Profile 1,4-Butanediol is heat and light sensitive. 1,4-Butanediol reacts with acid chlorides, acid anhydrides and chloroformates; reacts with oxidizing agents and reducing agents. 1,4-Butanediol is incompatible with isocyanates and acids; also incompatible with peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide and chlorine.

Purification Methods Distil the glycol and store it over Linde type 4A molecular sieves, or crystallise it twice from anhydrous diethyl ether/acetone, and redistil it. It has been recrystallised from the melt and doubly distilled in vacuo in the presence of Na2SO4. [Beilstein 1 IV 2515.]
 
 
 
Legality of 1,4-Butanediol:
 
While 1,4-butanediol is not currently scheduled federally in the United States, a number of states have classified 1,4-butanediol as a controlled substance. Individuals have been prosecuted for 1,4-butanediol under the Federal Analog . A federal case in New York in 2002 ruled, but that decision was later overturned by the Second Circuit. However, a Federal District Court in Chicago ruled, and the Seventh Circuit Court of Appeals upheld that ruling. In the United Kingdom, 1,4-butanediol was scheduled in December 2009 as a Class C controlled substance. In Germany, the drug is not explicitly illegal, but might also be treated as illegal if used as a drug. It is controlled as a Schedule VI precursor in Canada.
 
 
Industrial Use of 1,4-Butanediol:
 
1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry. In the presence of phosphoric acid and high temperature, it dehydrates to the important solvent tetrahydrofuran. At about 200 °C in the presence of soluble ruthenium catalysts, the diol undergoes dehydrogenation to form butyrolactone.
s
World production of 1,4-butanediol was claimed to be about one million metric tons per year and market price is about 2,000 USD (1,600 EUR) per ton (2005). In 2013, worldwide production was claimed to be billions of lbs (consistent with approximately one million metric tons).
