The substitution reaction of propylene and chlorine occurs at 500℃, which provides energy for the reaction at 500℃. Propylene produces free radicals, and chlorine gas becomes chlorine free radicals, and the two collide, so a substitution reaction takes place.
Chlorination of propylene at high temperature produces allyl chloride ch? =CHCH？ Cl is the raw material for synthesizing glycerol.
Extended data
1. Allyl chloride is a colorless and transparent liquid with unpleasant pungent smell. Slightly soluble in water, easily soluble in most organic solvents such as ethanol, ether, chloroform and petroleum ether. It is mainly used as an intermediate of drugs, pesticides and plastics. Store in a cool and ventilated warehouse. Stay away from fire and heat sources. The reservoir temperature should not exceed 29℃. The package should be sealed and not in contact with air.
2. Besides the ethylene bond, propylene can also react with methyl. Propylene is polymerized in the presence of acidic catalyst to form a mixture of dimer, trimer and tetramer, which can be used as high octane fuel. In the presence of Ziegler catalyst, propylene is polymerized to produce polypropylene. The products of propylene and ethylene polymerization are 3-chloropropene and hydrogen chloride.
