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
Isobutylene glycol may be considered a kind of butylene glycol, similarly to butane historically including n-butane and i-butane (isobutane). The modern name for the closely related type of compounds is methylpropanediol. There are two stable structural isomers: 2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol; and one unstable geminal diol:
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]
1,3-Butanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol . The compound without the R (or D) designation is racemic, which is what has been used in most studies before 2023.
DMT and 1,4-butanediol are also reacted to form their polyester (plus methanol). This polyester is then added to the butylene adipic acid polyester by using tetrabutoxytitanium (TBOT) as a transesterification catalyst; an overabundance of 1,4-butanediol influences chain lengths. The result is a copolymer of the two previously prepared polymers ...
It is produced by polymerization of tetrahydrofuran as well as 1,4-butanediol. The product is commercially available as polymers of low average molecular weights , between 250 and 3000 daltons . In this form it is a white waxy solid that melts between 20 and 30 °C.
