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
[1] [2] Genomatica’s process technology for the chemical 1,4-Butanediol (BDO) is now commercial. Genomatica produced 5 million pounds of renewable BDO in five weeks at a DuPont Tate & Lyle plant in Tennessee. [3] Its GENO BDO process has been licensed by BASF [4] and by Novamont. [5]
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 most important chain extenders are ethylene glycol, 1,4-butanediol (1,4-BDO or BDO), 1,6-hexanediol, cyclohexane dimethanol and hydroquinone bis(2-hydroxyethyl) ether (HQEE). All of these glycols form polyurethanes that phase separate well and form well defined hard segment domains, and are melt processable.
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.
BioAmber had a license from Johnson Matthey Davy Technologies a catalyst technology that converts bio-based succinic acid into bio-based 1,4-butanediol (BDO). [11] The technology involves the vapor phase hydrogenation of succinic acid ester into BDO and tetrahydrofuran (THF). [12]
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.
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]
