| | trans-1,4-Dichloro-2-butene Usage And Synthesis |
| 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. | | Synthesis Reference(s) | Journal of the American Chemical Society, 73, p. 2118, 1951 DOI: 10.1021/ja01149a061
The Journal of Organic Chemistry, 36, p. 2088, 1971 DOI: 10.1021/jo00814a013 | | 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. |
