Abstract

Straight chain saturated or ethylenically unsaturated hydrocarbons having up to 15 carbon atoms in the molecule are halofluorinated by reaction in the vapour phase at 200 DEG to 650 DEG C. simultaneously with HF and Cl2, Br2 or I2 in a reactor in the presence of elemental carbon and, at least when the process is the chlorofluorination of methane, in the absence of any metallic halide catalyst, the reaction being conducted at a pressure of at least 0.5 atmosphere and with a residence time of reactants in the reactor of 0.1 to 200 seconds. When a hydrocarbon containing 3-15 carbon atoms is chlorofluorinated it is possible, by suitable choice of reaction conditions, to cause degradation of the reaction products such that at least one chlorofluoromethane is obtained. When pentane is chlorofluorinated the reaction product may contain cyclic chlorofluoro compounds having a five-numbered carbon ring.
