Abstract
PURPOSE: To prepare 1,3-dichloropropene useful as raw materials for organic syntheses, in high yield, by the simultaneous pyrolysis and chlorination of 1,2- dichloropropane in the presence of allyl chloride and/or 1-chloropropene.
CONSTITUTION: 1,3-Dichloropropene is produced by rapidly contacting chlorine with a mixture of 1,2-dichloropropane and 30-60wt% of allyl chloride and/or 1- chloropropene at 450-570°C, thereby carrying out the simultaneous chlorination pyrolysis. Allyl chloride, etc. which are usually produced by the reaction, are preferably recovered together with unreacted components, and recycled and reused. Molar ratio of chlorine to the mixture of 1,2-dichloropropane and allyl chloride and/ or 1-chloropropene is 1 to 3-15, and the flow rate of the mixed gas is at least 10 m/ sec.
