Chemical properties

1,3-Dichloropropene is a colorless to strawcolored liquid. Sharp, sweet, irritating, chloroform-like odor.

The Uses of 1,1-DICHLOROPROPENE

1,1-Dichloropropene is useful in the preparation of novel 1,1-dichloropropene derivatives with insecticidal activity against Prodenia litura for Agricultural purposes.

Potential Exposure

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.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

storage

Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with 1,3-dichloropropene you should betrained on its proper handling and storage. Before enteringconfined space where this chemical may be present, checkto make sure that an explosive concentration does not exist.1,3-Dichloropropene must be stored to avoid contact withaluminum or magnesium compounds, substances containingfluorine, chlorine, bromine or iodine, and alkaline or corrosive materials, since violent reactions occur. Store in tightlyclosed containers in a cool, well-ventilated area away fromheat. Separate outside storage is preferred. Sources of ignition, such as smoking and open flames are prohibited where1,3-dichloropropene is handled, used, or stored. Metal containers involving the transfer of=gallons or more of 1,3-dichloropropene should be grounded and bonded. Drumsmust be equipped with self-closing valves, pressure vacuumbungs, and flame arresters. Use only nonsparking tools andequipment, especially when opening and closing containersof 1,3-dichloropropene. A regulated, marked area should beestablished where this chemical is handled, used, or storedin compliance with OSHA Standard 1910.1045.

Shipping

UN2047 Dichloropropene, Hazard Class: 3; Labels: 3-Flammable liquid.

Incompatibilities

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.
