  • Process and device for production of allyl chloride
    Patent number: 5367105
    Abstract: A process for the production of allyl chloride, which comprises introducing propylene and chlorine into a reactor having at least one propylene-injection opening and at least one chlorine-injection opening, these openings being independent of each other, through the respective injection openings, and reacting them in a vapor phase, wherein propylene and chlorine are introduced into the reactor by injecting them in almost the same direction from the propylene-injection opening and the chlorine-injection opening which is closest to said propylene-injection opening, with a linear velocity in the propylene-injection opening, calculated as a value of at 300.degree. C. and 1 kg/cm.sup.2.G, of 100 m/sec or higher and a linear velocity of the chlorine-injection opening, calculated as a value of at 100.degree. C. and 1 kg/cm.sup.2.G, of 70 m/sec or higher, and the propylene-injection opening and the chlorine-injection opening are situated to meet the following expression (1),0.5.ltoreq.L/(dp+dc).ltoreq.
