DICHLOROBUTENE Chemical Properties,Uses,Production
Chemical Properties
The 1,4-dichloro-2-butenes are colorless liquids. Some have a distinct odor. (cis-isomer)
Safety Profile
A flammable liquid. When heated to decomposition it emits toxic vapors of Cl-
Potential Exposure
DC occurs as a by-product in chloroprene manufacture and may be used as a chemical intermediate
Shipping
UN3384 Toxic by inhalation liquid, flammable, n. o.s. with an LC50 ≦ 1000 ml/m3 and saturated vapor concentration ≧to 10 LC50, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 3-Flammable liquid, Technical Name Required, Inhalation Hazard Zone B. UN2920 Corrosive liquids, flammable, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, 3-Flammable liquid. The code “D” identifies proper shipping names which are appropriate for describing materials for domestic transportation but may be inappropriate for international transportation under the provisions of international regulations, e.g., IMO, ICAO). An alternate proper shipping name may be selected when either domestic or international transportation is involved
Incompatibilities
Vapors 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. (cis-isomer): Reacts slowly with water forming hydrogen chloride. Attacks metals and may form other, more dangerous materials; attacks some plastics.
Waste Disposal
High-temperature incineration with hydrochloric acid scrubbing. 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.
