Environmental behaviour

At 20 0C, cis-1,3-dichloropropene is a liquid denser than water and moderately volatile. Characterized by moderate solubility, it will volatilize rapidly once dissolved and adsorbs moderately to organic matter. During a spill, this compound will evaporate in part but may also enter into the soil or migrate into a waterway. Once it encounters water (surface or subsurface), cis-1,3-dichloropropene will dissolve or sink until it reaches an impermeable surface. The liquid cis-1,3-dichloropropene that accumulates in a saturated zone will gradually dissolve before volatilization occurs. The adsorbed cis-1,3-dichloropropene in the vadose and saturated zones will gradually disappear, liberating contamination in either the gaseous or dissolved state. The resulting plumes (gaseous or dissolved) will be moderate in size.

Health and safety

cis-1,3-Dichloropropene should be handled with care as it is flammable and toxic.

Principal resources

All commercial preparations of 1,3-dichloropropene are mixtures of the cis-and trans-isomers. 1,3-Dichloropropene is produced industrially by either high-temperature chlorination of propene or by dehydration of 1,3-dichloro-2-propanol. 1,3-Dichloropropene is the predominant component in many soil fumigants used in the control of plant-parasitic nematodes in agriculture. Most of these fumigants are not diluted and are applied directly to the soil for vegetable and tobacco crops. Much smaller quantities of 1,3-dichloropropene are used as solvents and chemical intermediates.
