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
Butanediol, also called butylene glycol, may refer to any one of four stable structural isomers: 1,2-Butanediol; 1,3-Butanediol; 1,4-Butanediol; 2,3-Butanediol ...
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]
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-Butanedithiol is an organosulfur compound with the formula HSCH 2 CH 2 CH 2 CH 2 SH. It is a malodorous, colorless liquid that is highly soluble in organic solvents. It is a malodorous, colorless liquid that is highly soluble in organic solvents.
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 .
γ-Butyrolactone is produced industrially by dehydrogenation of 1,4-butanediol at a temperature of 180–300 °C and atmospheric pressure in the presence of a copper catalyst. [5] The yield of this process is approximately 95%. The purification takes place with a liquid-gas-phase extraction. [5]
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]
