1,4-Butanediol, also called Butane-1,4-diol (other names include 1,4-B, BD, BDO and 1,4-BD), [5] is a primary alcohol and an organic compound with the formula HOCH 2 CH 2 CH 2 CH 2 OH. . It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glyco
2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol; and one unstable geminal diol: 2-methylpropane-1,1-diol (not a glycol), hydrate of 2-methylpropanal (isobutyraldehyde) These three methylpropanediols are structural isomers of butanediols. They are not chiral.
Alkylation with geminal dihalides gives 1,3-dithiepanes. Oxidation gives the cyclic disulfide 1,2-dithiane: [3] HSCH 2 CH 2 CH 2 CH 2 SH + O → S 2 (CH 2) 4 + H 2 O. It forms self-assembled monolayers on gold. [4] It is also used in polyadditions along with 1,4-butanediol to form sulfur-containing polyester and polyurethanes containing ...
Legislation entering into force on 1 April 2011 made it possible to handle narcotics for industrial purposes and enabled GBL and 1,4-Butanediol to be classified as controlled substances. [39] As of 2023 there are penalties for possessing, selling or driving under the influence of the substance. [40]
United States v. Washam (2002) 312 F.3d 926, 930 was an appellate decision for the eighth judicial circuit in which it was considered whether the drug 1,4-Butanediol (1,4-B) was a controlled substance analogue in the United States. The controlled drug which it was alleged 1,4-B was substantially similar to was gamma-hydroxybutyrate (GHB). 1,4-B GHB
1,4-Butynediol is a precursor to 1,4-butanediol and 2-butene-1,4-diol by hydrogenation. It is also used in the manufacture of certain herbicides, textile additives, corrosion inhibitors, plasticizers, synthetic resins, and polyurethanes. It is the major raw material used in the synthesis of vitamin B 6. [5]
The direct esterification of succinic acid with 1,4-butanediol is the most common way to produce PBS. It consists of a two step process. It consists of a two step process. First, an excess of the diol is esterified with the diacid to form PBS oligomers with elimination of water .
