2-Butanol Uses

2-Butanol (CAS NO.15892-23-6) is used as a solvent, it is mainly converted to butanone ("MEK"), which is an important industrial solvent and found in many domestic cleaning agents and paint removers. Volatile esters of 2-butanol have pleasant aromas and are used in small amounts as perfumes or in artificial flavors.

2-Butanol Production

Raw materials: 1,3-Butadiene --> N-Butane --> Petroleum Ether --> Sec-Butanol --> Di-N-Butyl Sulfate --> Cis-2-Butene --> 2-Butene

2-Butanol Specification

2-Butanol (CAS NO.15892-23-6) is a flammable, colorless liquid that is soluble in 12 parts water and completely miscible with polar organic solvent such as ethers and other alcohols. It is produced on a large scale, primarily as a precursor to the industrial solvent methyl ethyl ketone.It is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-2-butanol and (S)-(+)-2-butanol. It is normally found as an equal mixture of the two stereoisomers — a racemic mixture.
