4chloro1butene

4-Chloro-1-butene is an organochlorine compound with the chemical formula C4H7Cl. It is a colorless liquid with a distinct odor. This compound is a derivative of butane, where a chlorine atom is attached to the fourth carbon and a double bond exists between the first and second carbons.

The synthesis of 4-chloro-1-butene can be achieved through various methods. One common route involves the reaction of 1,3-butadiene with hydrogen chloride. This addition reaction typically occurs under specific conditions, often involving catalysts, to favor the desired product over other possible isomers. Another method might involve the chlorination of butene derivatives.

Industrially, 4-chloro-1-butene serves as an intermediate in the synthesis of other chemical compounds. Its reactive nature, due to the presence of both a double bond and a chlorine atom, makes it a versatile building block. It is particularly important in the production of certain polymers and specialty chemicals. For instance, it can be polymerized to form poly(4-chloro-1-butene), although this is not a widely commercialized polymer. It is also used in the synthesis of pharmaceuticals and agrochemicals.

Due to its chemical properties, 4-chloro-1-butene is considered a flammable liquid and should be handled with appropriate safety precautions. It may also be an irritant. Environmental considerations regarding its production and use are also relevant, as organochlorine compounds can have varying degrees of persistence and toxicity.
