cis-1,4-Dichloro-2-butene - Introduction
cis-1,4-Dichloro-2-butene, also known as 1,4-dichlorobutadiene or 1,4-dichlorobutene, is an organic compound. Its chemical formula is ClCH2CH2CH = CHCl. In the structure, two chlorine atoms are connected to carbons 1 and 4 of a butene molecule. The alkenyl group of butene is in the same plane as the chlorine atom, hence the name CIS.
The following is some information on the properties, uses, preparation and safety of cis-1,4-Dichloro-2-butene:
Nature:
-Appearance: colorless liquid
-Density: 1.19g/cm³
-Melting point:-51 ° C
-Boiling point: 139-141 ° C
-Solubility: Soluble in organic solvents such as alcohols, ethers and aromatic hydrocarbons, difficult to dissolve in water
-Stability to air and light: Easy to decompose under light, and also decompose when heated
Use:
