At 20 0C, trans-1,3-dichloropropene is a liquid denser than water and very 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),
the trans-1,3-dichloropropene will dissolve or sink until it reaches an impermeable surface. The
liquid trans-1,3-dichloropropene that accumulates in a saturated zone will gradually dissolve before
volatilization occurs. The adsorbed trans-1,3-dichloropropene in the vadose and saturated zones will
take time to disappear, liberating contamination in either the gaseous or dissolved state. The
resulting plumes (gaseous or dissolved) will be moderate in size.
Trans-1,3-Dichloropropene should be handled with care as it is flammable and toxic.
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.
