    摘要： An improved process for the liquid phase chlorination of a normally liquid hydrocarbon mixture is provided which is capable of yielding a product of enhanced quality through the elimination of an undesirable side reaction in the gaseous mixture which is in contact with the liquid mass where the desired chlorination reaction is carried out. The hydrocarbon feed contains on the average 6 to 18 carbon atoms per molecule and consists mainly of normal alpha-olefins. A minor quantity of an additive (e.g. carbon tetrachloride) is provided in the reaction zone and is at least partially present in the gaseous mixture where an undesirable reaction between hydrocarbon vapor and gaseous chlorine is eliminated. An improved chlorinated hydrocarbon product is formed in the reaction zone.

    摘要： A PROCESS FOR THE PRODUCTION OF TRICHLOROPROPANES BY REACTION OF PROPENE, HYDROGEN CHLORIDE AND OXYGEN IN A MOLAR RATIO OF PROPENE/O2/HCL OF 1/0.65 TO 1.40/2.0 TO 6.5 AT A TEMPERATURE WITHIN THE THE RANGE OF 170* TO 370* C. IN THE PRESENCE OF A FIXED BAD CATALYTIC MASS HAVING A COMPOUND OF COPPER AS THE PRINCIPAL ACTIVE AGENT DEPOSITED ON A CATALYST SUPPORT HAVING A SPECIFIC SURFACE WITHIN THE RANGE OF 1 TO 300 M.2/G. AND IN WHICH THE MAXIMUM TEMPERATURE REACHED IN THE INTERIOR OF THE CATALYTIC MASS IS 30* TO 200* ABOVE THE WALL TEMPERATURE OF THE REACTOR AND IN WHICH THE MATERIALS ARE REACTED AT A FLOW RATE OF 1 TO 100 MOLES OF PROPENE PER LITER OF CATALYTIC PER HOUR.
