TERATHANE polytetramethylene ether glycol (PTMEG), 1,4 butanediol
(BDO), and tetrahydrofuran (THF) production
"The opportunity to expand the range of products and applications made from renewable raw materials allows us and our partners to further explore the long-term market acceptance of this innovative technology." PolyTHF is derived from 1,4 butanediol
(BDO), which BASF has produced under license from Genomatica.
Major succinic acid applications elucidated in this study includes 1,4 butanediol
, polyurethane, plasticizers, resins, coatings, dyes & inks, pharmaceutical, food, cosmetics, solvents and lubricants, se-icing solutions, and others.
The Home Office said it now intends to control the two chemicals, known as Gamma-butyrolactone (GBL) and 1,4 butanediol
(1,4-BD) as Class C drugs after a consultation period.

Another chemical, 1,4 BD (1,4 butanediol
) has also appeared on the illicit drug scene.
This was always the case for 1,4 butanediol
where the monomeric material oiled the surface layer and would not disperse properly.
The supplements contain industrial chemicals such as 1,4 butanediol
(BD), a substance that was associated with all 3 reported deaths and with dangerously low respiratory rates, unconsciousness, vomiting, and seizures.
Prices for 1,4 Butanediol
(BDO) will increase by eight cents per pound; prices for N-Methyl-2-Pyrrolidone (NMP), N-Ethyl-2-Pyrrolidone (NEP) and Gamma-Butyrolactone (BLO) will increase by 10 cents per pound; and prices for Tetrahydrofuran (THF) will increase by 12 cents per pound.
Du Pont will increase off-list prices of 1,4 butanediol
(BDO), tetrahydrofuran (THF) and Terathane polytetramethylene ether glycol (PTMEG) effective October 1, or as contractual agreements permit.

and its derivatives in the U.S., Canada and Mexico; $0.10/lb.
The hard segment is typically based on methylene diisocyanate (MDI) and 1,4 butanediol
. When color retention under UV exposure is critical, an aliphatic diisocyanate is substituted for MDI.
