Allyl chloride is the organic compound with the formula CH2=CHCH2Cl. This colorless liquid is insoluble in water but soluble in common organic solvents.

A clear colorless liquid with an unpleasant pungent odor. Flash point -20°F. Boiling point 113°F. Less dense than water (7.8 lb / gal) and insoluble in water.

ALLYL CHLORIDE is highly flammable when exposed to heat, flame or oxidizing agents. Polymerizes violently and exothermically with Lewis acids (aluminum chloride, boron trifluoride, sulfuric acid) or metals (aluminum, magnesium, zinc, or galvanized metal). Incompatible with acids (nitric acid, chlorosulfonic acid, oleum), with strong bases (sodium hydroxide, potassium hydroxide), with ethyleneimine and ethylenediamine. Attempts to alkylate benzene or toluene using allyl chloride in the presence of ethylaluminum chlorides have led to explosions
