This nematocide is used as a sol fumigant prior to crop
cultivation. Mainly farmers and process operators
employed at pesticide plants are exposed.

化学的特性
1,3-Dichloropropene is a colorless to strawcolored liquid. Sharp, sweet, irritating, chloroform-like odor.
-
使用
1,3-Dichloropropene (a technical-grade mixture of the cis-and transisomers) is used as a preplanting fumigant, mainly for the control of nematodes affecting the roots of plants, selected plant diseases, garden centipedes, wireworms, and weeds; as a solvent; and as an intermediate in the manufacture of 3,3-dichloro-1-propene and other pesticides. It is registered for use on all vegetable, fruit, and nut crops, all forage crops, tobacco, all fiber crops, and all nursery crops (EPA 1998). In Hawaii, 1,3-dichloropropene is used to control nematodes on pineapples at planting (Albrecht 1987). In 2009, three products containing 1,3-dichloropropene as an active ingredient were registered for restricted, non-residential use in the United States (EPA 2009). No products containing 1,3-dichloropropene are registered for use by homeowners (EPA 1998).

調製方法
1,3-DCP is produced either by high-temperature chlorination
of propylene or from 1,3-dichloro-2-propanol by dehydration
with phosphoryl chloride or phosphorus pentoxide in
benzene. All commercial preparations of 1,3-DCP are mixtures
of the cis- and trans-isomers.
According to SRI Consulting, Dow AgroSciences LLC
(Freeport, Texas) is the only current manufacturer of 1,3-
DCP. Active registrants of 1,3-DCP pesticide formulations
include Dow AgroSciences LLC (Indianapolis, Indiana),Soil Chemicals Corporation (Hollister, California), and
Trical (Hollister, California).

空気と水の反応
Highly flammable. Insoluble in water.
-
反応プロフィール
1,3-Dichloropropene reacts vigorously with oxidizing materials. Reacts with aluminum, active metals, and halogenated compounds. Also reacts with acids and thiocyanates. Corrosive to magnesium, magnesium alloys and aluminum alloys. Incompatible with some metal salts .
-
健康ハザード
VAPOR: Irritating to eyes, nose and throat. LIQUID: Will burn skin and eyes. Harmful if swallowed.
-
火災危険
FLAMMABLE. POISONOUS GASES ARE PRODUCED IN FIRE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area. Toxic and irritating gases may be generated.

农业用途
Soil fumigant, Nematicide: This chemical is also used in combinations with
dichloropropanes as a soil fumigant to kill nematodes,
insects and fungus on cotton, potatoes, tobacco, sugar
beets, vegetables, grain, citrus planting sites, deciduous
fruit and nut-tree planting sites, and ornamental trees and
floral sites. Top four applications in California are on
sweet potatoes, carrots, wine grapes and outdoor propagation
nurseries. It is used on a wide variety of crops. Not
approved for use in EU countries. Actively registered
in the U.S.

発がん性
Technical-grade 1,3-dichloropropene (co
ntaining 1.0% epichlorohydrin as a stabilizer) is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals. The technical-grade 1,3-dichloropropene used in the cancer studies in experimental animals was a mixture of cis- and trans-isomers and varied in purity and the stabilizer used (see Properties).
-
代謝経路
Degradation of 14C-1,3-dichloropropene in aerobic
soils in the dark at 25℃ at concentration of
approximately 100 μg g-1 results in the formation of 3-chloroallyl alchohol, 3-chloroacrylic acid, numerous
minor carboxylic acid metabolites, and carbon dioxide.
In addition, there is extensive incorporation of 14C
labeled material into the soil organic matter in the
soils. By a specific bacterium (Pseudomonas cichorii
170) which is isolated from soil, 1,3-dichloropropene is
degraded in different pathways from those of soil
degradation. The terminal degradate by this bacterium
is acetoaldehye which undergoes mineralization.

不和合性
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.

廃棄物の処理
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.
