摘要： Processes are disclosed for decreasing the chlorine to carbon ratio for halogenated hydrocarbons containing chlorine and from 1 to 6 carbon atoms, in the presence of a multiphase catalyst. The processes each involve (1) preparing a single phase solid catalyst precursor which has a structure that collapses at a temperature of about 400.degree. C. or less and has the formula (NH.sub.3).sub.6 Ru.sub.l-r-s Co.sub.r Cr.sub.s MF.sub.6, where r+s is in the range of 0.00 to 0.99, and M is at least one trivalent metal selected from the group consisting of Al, Cr, Fe, V, Sc and Ga; and (2) producing the multiphase catalyst by heating the single phase solid catalyst precursor to about 400.degree. C. or less in an non-oxidizing atomsphere to produce a multiphase composition wherein a phase containing ruthenium is homogeneously dispersed with a phase containing metal fluoride.Also disclosed are single phase fluoride compositions having the formula (NH.sub.3).sub.6 Ru.sub.l-r-s Co.sub.r Cr.sub.s MF.sub.6, where r+s is in the range of 0.00 to 0.99, and M is at least one trivalent element selected from the group consisting of Al, Cr, Fe, V, Sc and Ga; and multiphase catalyst compositions consisting essentially of metallic ruthenium and fluorides of at least one element selected from the group consisting of Al, Co, Cr, Fe, V, Sc and Ga, wherein the ruthenium is homogeneously dispersed with phases of the fluorides.
