Butyraldehyde, also known as butanal, is an organic compound with the formula CH 3 (CH 2) 2 CHO. This compound is the aldehyde derivative of butane . It is a colorless flammable liquid with an unpleasant smell.
It is an aldehyde, isomeric with n-butyraldehyde (butanal). [1] Isobutyraldehyde is made, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw. It undergoes the Cannizaro reaction even though it has alpha hydrogen atom. It is a colorless volatile liquid.
[2] 2-ethylhexanol is however more easily prepared by alternative methods (from butyraldehyde by aldol condensation). Instead, the Guerbet reaction is mainly applied to fatty alcohols to afford oily products, which are called Guerbet alcohols. They are of commercial interest to as components of cosmetics, plasticizers, and related applications.
The acute toxicity of 1-butanol is relatively low, with oral LD 50 values of 790–4,360 mg/kg (rat; comparable values for ethanol are 7,000–15,000 mg/kg). [ 8 ] [ 32 ] [ 11 ] It is metabolized completely in vertebrates in a manner similar to ethanol : alcohol dehydrogenase converts 1-butanol to butyraldehyde ; this is then converted to ...
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.
It is a chemical intermediate in the biosynthesis of the neurotransmitter γ-hydroxybutyric acid (GHB) from 1,4-butanediol (1,4-BD). [2] Like 1,4-BD, it also behaves as a prodrug to GHB when taken exogenously.
Polypropylene end uses include films, fibers, containers, packaging, and caps and closures. Propene is also used for the production of chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde, and acrylic acid. In the year 2013 about 85 million tonnes of propylene were processed worldwide. [17]
