Chemical Properties
The 1,4-dichloro-2-butenes are colorless
liquids. Some have a distinct odor. (cis-isomer)
Chemical Properties
clear colorless to light yellow liquid
Uses
1,4-Dichloro-2-butene is used in the synthesis of anthraquinones used in the asymmetric dihydroxylation of olefins. Also used to prepare arylcarboxamides used as novel dopamine receptor antagonists.
Definition
ChEBI: Trans-1,4-Dichlorobutene is an organochlorine compound.
General Description
Colorless liquid with a distinct odor. An intermediate for hexamethylenediamine and chloroprene.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
trans-1,4-Dichloro-2-butene will burn, though trans-1,4-Dichloro-2-butene may require some effort to ignite. Fire produces irritating and poisonous gases. When heated to decomposition, trans-1,4-Dichloro-2-butene emits toxic fumes of chlorine-containing compounds. [EPA, 1998].
Health Hazard
(Non-Specific -- Dichlorobutene) Liquid and vapors from the material are highly corrosive and may damage skin, eyes, lungs, and internal organs.
Fire Hazard
The material will burn, though trans-1,4-Dichloro-2-butene may require some effort to ignite. Fire produces irritating and poisonous gases. When heated to decomposition, trans-1,4-Dichloro-2-butene emits toxic fumes of chlorine-containing compounds.
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.
