Heat of combustion: -17,500 Btu/lb = -9,720 cal/g = -407x10+5 J/kg /Dichlorobutene/|Heat of vaporization: 130 Btu = 73 cal/g = 3.1x10+5 J/kg /Dichlorobutene/

Highly flammable. Reacts slowly with water to form hydrochloric acid. Insoluble in water.

Halogenated Organic Compounds

Highly Flammable

Halogenated unsaturated aliphatic compounds, such as 1,4-DICHLORO-2-BUTENE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
