The 1,4-dichloro-2-butenes are colorless
liquids. Some have a distinct odor. (cis-isomer)
A flammable liquid.
When heated to decomposition it emits
toxic vapors of Cl-
DC occurs as a by-product in chloroprene manufacture and may be used as a chemical
intermediate
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
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.
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.
