Chemical Structure of Chloroprene

Chloroprene is the common name for the organic compound 2-chloro-1,3-butadiene, which has the chemical formula C₄H₅Cl. The chemical structure is shown at right. It is used as monomer for the production of the polymer polychloroprene, a type of synthetic rubber. Polychloroprene is better known to the public as Neoprene, the trade name DuPont gave it when the company first developed it and currently used by DuPont Dow.

Production of chloroprene

The acetylene process was used to produce chloroprene until the 1960s. In this process, acetylene and hydrogen chloride were used as shown here: The chemical compound acetylene, also called ethyne, was discovered in 1836 by Edmund Davy, in England; its chemical formula is C2H2 and its structure is: Acetylene is a colorless and extremely flammable gas at standard temperature and pressure, with a melting point of -80. ... Hydrogen chloride, also known under the name HCl, is a highly corrosive and toxic colorless gas that forms white fumes on contact with humidity. ...

This process had disadvantages in that it was very energy-intensive and had high investment costs.

The modern chloroprene process which is currently used by nearly all makers uses butadiene differently. 1,3-Butadiene undergoes addition of chlorine across one of its double bonds in its molecule to give 3,4-dichloro-1-butene. Then this compound undergoes an elimination of a hydrogen atom in the #3 position and the chlorine atom in the #4 position as HCl forming a double bond between the #3 and #4 carbon atoms in the molecule, yielding chloroprene. Butadiene can refer to either one of two hydrocarbon chemical compounds which are alkenes that are isomers of each other. ...

Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together. ... A molecule is the smallest particle of a pure chemical substance that still retains its chemical composition and properties. ... Properties For alternative meanings see atom (disambiguation). ...
