Beschreibung
Trans-1,3-dichloropropene appears as a clear colorless liquid with chloroform odor. Flash point 95 °F. Density 1.225 g/cm3 and insoluble in water. Hence sinks in water. A strong irritant. Used as a soil fumigant. It is used as an intermediate in the manufacture of 3,3-dichloro-1-propene and other pesticides.
Chemische Eigenschaften
colourless liquid
Physikalische Eigenschaften
Colorless to pale yellow liquid with a chloroform-like odor. Evaporates quickly when spilled.
Verwenden
The isomer mixture is used as a soil fumigant and a nematocide.
Allgemeine Beschreibung

Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivit?t anzeigen
trans-1,3-Dichloropropene reacts with aluminum, aluminum alloys, with other active metals and with some metal salts and halogens. Can react vigorously with oxidizing materials. .
Brandgefahr
Flash point data for trans-1,3-Dichloropropene are not available, however literature indicates that trans-1,3-Dichloropropene is flammable.
m?gliche Exposition
Used as a soil fumigant prior to
planting crops, such as cotton, sugar beet, potatoes; used in
combinations with dichloropropanes as a soil fumigant.
Workers engaged in manufacture, formulation and application of this soil fumigant and nematocide.
Environmental Fate
Biological. The isomeric mixture showed significant degradation with gradual adaptation
in a static-culture flask-screening test (settled domestic wastewater inoculum) conducted
at 25°C. At concentrations of 5 and 10 mg/L, percent losses after 4 weeks of
incubation were 85 and 84, respectively. Ten days into the incubation study, 7–19% was
lost due to volatilization (Tabak et al., 1981).
Chemical/Physical. Hydrolysis in distilled water at 25°C produced trans-3-chloro-2-
propen-1-ol and hydrochloric acid. The reported half-life for this reaction is only 2 days (Kollig, 1993; Milano et al., 1988). trans-1,3-Dichloropropylene was reported to hydrolyze
to 3-chloro-2-propen-1-ol and can be biologically oxidized to 3-chloropropenoic acid
which is further oxidized to formylacetic acid. Decarboxylation of this compound yields
carbon dioxide (Connors et al., 1990). Chloroacetaldehyde, formyl chloride and chloroacetic
acid were formed from the ozonation of dichloropropylene at approximately 23°C
and 730 mmHg. Chloroacetaldehyde and formyl chloride also formed from the reaction
of dichloropropylene and hydroxyl radicals (Tuazon et al., 1984).
The evaporation half-life of trans-1,3-dichloropropylene (1 mg/L) from water at 25°C
using a shallow-pitch propeller stirrer at 200 rpm at an average depth of 6.5 cm is 24.6
minutes (Dilling, 1977).
Emits chlorinated acids when incinerated. Incomplete combustion may release toxic
phosgene (Sittig, 1985).

UN2047 Dichloropropene, Hazard Class: 3;
Labels: 3-Flammable liquid.
Inkompatibilit?ten
Vapor may form explosive mixture
with air. Incompatible with oxidizers (chlorates, nitrates,
peroxides, permanganates, perchlorates, chlorine, bromine,
fluorine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, and epoxides. May accumulate static electrical
charges, and may cause ignition of its vapors. Incompatible
with strong acids; oxidizers, aluminum or magnesium compounds; aliphatic amines; alkanolamines, alkaline materials;
halogens, or corrosives. Note: Epichlorohydrin may be
added as a stabilizer.
Waste disposal
Incineration, preferably
after mixing with another combustible fuel. Care must be
exercised to assure complete combustion to prevent the
formation of phosgene. An acid scrubber is necessary to
remove the halo acids produced. In accordance with
40CFR165, follow recommendations for the disposal of
pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting
your local or federal environmental control agency, or by
contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on
acceptable disposal practices. Generators of waste containing this contaminant (≧100 kg/mo) must conform with
EPA regulations governing storage, transportation, treatment, and waste disposal.
