2-Butene-1,4-diol Usage And Synthesis

Description

2-Buten-1,4-diol is a palladium-containing compound that forms cross-links by reacting with an oxygen nucleophile. It reacts with nitrogen nucleophiles in the presence of hydrochloric acid to provide gamma-aminobutyric acid. This reaction mechanism is analogous to the way in which amines react with carboxylic acids to form amides. cis,trans-2-Buten-1,4-diol can be found in kinetic studies and its nmr spectra have been studied extensively.

Chemical Properties

Colorless to light yellow liquid

Uses

It is used to make agricultural chemicalsand the pesticide endosulfan; and as anintermediate for making vitamin B.

Application

2-Butene-1,4-diol has been used as a cross-linking agent for various polymers and is also able to form hydroxyl groups through allylation reactions.

Reactivity Profile

2-Butene-1,4-diol forms furan (narcotic)when treated with dichromate in acidic solution.Dehydration of the cis-isomer overacid catalysts yields 2,5-dihydrofuran (narcotic).Halogens form substitution or additionproducts, 4-halobutenols, or 2,3-dihalo-1,4-butanediol. These are toxic compounds.Ammonia or amine form pyrroline or itsderivatives (moderately toxic).

Health Hazard

2-Butene-1,4-diol is a depressant of the Centralnervous system. Inhalation toxicity isvery low due to its low vapor pressure. Theoral LD50 value in rats and guinea pigs is1.25 mL/kg. It is a primary skin irritant.

Fire Hazard

Noncombustible liquid; flash point (open cup) 128°C.
