Butylene oxide

Butylene oxide, like propylene oxide, is produced by the chlorohydrination of l-butene with HOCl followed by epoxidation. The reaction conditions are similar to those used for propylene:

Butylene oxide may be hydrolyzed to butylene glycol, which is used to make plasticizers. 1,2-Butylene oxide is a stabilizer for chlorinated solvents and also an intermediate in organic synthesis such as in surfactants and pharmaceuticals.
