ABSTRACT:
A process is disclosed for producing saturated halohydrocarbons containing fluorine which comprises the step of reacting certain saturated or olefinic compounds at an elevated temperature with hydrogen in the presence of at least one material selected from the group consisting of iodine and hydrogen iodide, or with hydrogen iodide. Also disclosed s a process for producing certain chloromethanes which comprises the step of reacting CCl.sub.4 at an elevated temperature with hydrogen in the presence of iodine and/or HI, or with hydrogen iodide; and a process for producing CF.sub.3 CCl.dbd.CHCF.sub.3 which comprises the step of reacting CF.sub.3 CCl.dbd.CClCF.sub.3 at an elevated temperature with hydrogen in the presence of iodine and/or HI, or with hydrogen iodide.
