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
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 ...
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]
1,4-Butanediol diglycidyl ether (B14DODGE) is an organic chemical in the glycidyl ether family. It is aliphatic and a colorless liquid. It has two epoxide (oxirane) groups per molecule. [1] Its main use is in modifying epoxy resins especially viscosity reduction. [2] It is REACH registered. [3] The IUPAC name is 2-[4-(oxiran-2-ylmethoxy ...
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.
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. First, an excess of the diol is esterified with the diacid to form PBS oligomers with elimination of water.
The most widely used industrial process involves the acid-catalyzed dehydration of 1,4-butanediol. Ashland/ISP is one of the biggest producers of this chemical route. The method is similar to the production of diethyl ether from ethanol. The butanediol is derived from condensation of acetylene with formaldehyde followed by hydrogenation. [8]
The toy consists of small beads that stick to each other upon sprinkling with water. 1,4-Butanediol, which when ingested is metabolized to gamma-hydroxybutyric acid, was detected by GC-MS. [7] [8] ChemNet China lists the price of 1,4-butanediol at between about US$1,350–2,800/tonne, while the price for 1,5-pentanediol is about US$9,700/tonne. [9]
