Characteristics

PSA：

XLogP3：

2.1

Appearance：

Allyl chloride appears as 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. Hence floats on water. Vapor irritates skin, eyes and mucous membranes. Vapors are heavier than air. Long exposure to low concentrations or short exposure to high concentrations may have adverse health effects from inhalation or skin absorption.

Allyl chloride Use and Manufacturing

Methods of Manufacturing

The preparation method includes high temperature chlorination method, propylene oxychlorination method, allyl alcohol chlorination method and the like. The high temperature chlorination method is produced by the high temperature of propylene. Reaction equation: CH3CH=CH2+Cl2→ClCH2CH=CH2+HCl preheats dry propylene at 350～400℃, liquid chlorine is heated and gasified, the two materials are mixed and reacted under the condition of high-speed injection, and the propylene and chlorine gas The mixing ratio is 4-5:1 (molar ratio), the reactor residence time is 1.5-2s, and the reaction temperature is 470-500°C. The reaction product is quenched to 50-100°C to remove HCl and propylene, and then fractionated to obtain the product. This method is adopted by most domestic and foreign manufacturers. The propylene oxychlorination method uses propylene, hydrogen chloride and oxygen mixed in a ratio of 2.5～ (1:1:1)～0.2 (molar ratio) to react in a fluidized bed reactor, and the catalysts selected are Te and V2O5 supported on a carrier Or H3PO4, and add nitrogen-containing substances as accelerators, and carry out atmospheric oxychlorination reaction at 240-260°C to obtain 3-chloropropene. Reaction equation: CH3CH=CH2+HCl+1/2O2[Catalyst]→CH2=CHCH2Cl+H2O Allyl alcohol chlorination reaction equation: CH2=CHCH2OH[Cu2Cl2, HCl]→CH2=CHCH2Cl+H2O at 10～20℃ Sulfuric acid was dropped into allyl alcohol, cuprous chloride and hydrochloric acid. After the dropwise addition was completed, the reaction was held for 5 hours, and then left to stand for separation. The supernatant was washed once with water, 5% sodium carbonate solution, and water. The fraction above 40°C is collected as 3-chloropropene. This method is suitable for small batch production.
