Mildly toxic by
inhalation. Mutation data reported. Very
dangerous fire hazard when exposed to heat,
flame, sparks, or powerful oxidizers. To
fight fire, use water, spray, mist, fog, dry
chemical, alcohol foam. When heated to
decomposition it emits toxic fumes of Cl-.

| Hazard Information | Back Directory | [General Description]
A clear colorless volatile liquid. Flash point-4°F., Boiling point 73°F. Less dense than water and insoluble in water. Vapors heavier than air. | [Reactivity Profile]
Halogenated aliphatic compounds, such as 2-CHLOROPROPENE(557-98-2), are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Low molecular weight haloalkenes are highly flammable, peroxidizable and may polymerize violently. They may react violently with aluminum. 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. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Health Hazard]
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | [Fire Hazard]
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | [Chemical Properties]
CLEAR COLOURLESS LIQUID | [Uses]
2-Chloropropene is used in measurement of photoionization cross sections of allyl and 2-propenyl radicals to form C3H5+ by tunable vacuum ultraviolet synchrotron radiation coupled with photofragment translational spectroscopy. | [Preparation]
1,2-Propadiene adds hydrogen chloride to yield 2-chloropropene. One early synthesis involves dehydrohalogenation of 1,2-dichloropropane with potassium hydroxide. |
