    Abstract: Carbon monoxide is produced by contacting a mixture of methane, hydrogen chloride and oxygen or a gas containing molecular oxygen with an iron phosphate catalyst at a temperature of 300 DEG to 700 DEG C. Phosphates of other metals, especially of Cu, Co, Ni, Cr, Pb, Ce, Mn, Bi, Mg, Cd or V, may also be present, the mole ratio of the phosphate of iron to the phosphate of the other metal being at least 1 : 1. Specified types of phosphate are orthophosphates, polyphosphates, metaphosphates, ultraphosphates, pyrophosphates, monohydrogen phosphates and dihydrogen phosphates. The catalyst may be used in an unsupported or supported form, specified carriers being diatomaceous earths, silica, silica gel, pumice, alumina, clay and porous brick. Examples are given.ALSO:Chlorinated methanes are produced by contacting a mixture of methane, hydrogen chloride and oxygen or a gas containing molecular oxygen with an iron phosphate catalyst at a temperature of 300 to 700 DEG C. Phosphates of other metals, especially of Cu, Co, Ni, Cr, Pb, Ce, Mn, Bi, Mg, Cd or V, may also be present, the mole ratio of the phosphate of iron to the phosphate of the other metal being at least 1:1. Specified types of phosphate are orthophosphates, polyphosphates, metaphosphates, ultraphosphates, pyrophosphates, monohydrogen phosphates and dihydrogen phosphates. The catalyst may be used in an unsupported or supported form, specified carriers being diatomaceous earths, silica, silica gel, pumice, alumina, clay and porous brick. Examples are given.ALSO:A catalyst for the oxychlorination of methane to chlorinated methanes (see Division C2) and carbon monoxide (see Division C1) comprises an iron phosphate. Phosphates of other metals, especially of Cu, Co, Ni, Cr, Pb, Ce, Mn, Bi, Mg, Cd and V, may also be present and serve as promoters or activators, the mole ratio of the phosphate of iron to the phosphate of the other metal being at least 1 : 1. The catalyst may be unsupported or supported on carriers such as diatomaceous earths, silica, silica gel, pumice, alumina, clay and porous brick. Specified types of phosphate are orthophosphates, polyphosphates, metaphosphates, ultraphosphates, pyrophosphates, monohydrogen phosphates and dihydrogen phosphates. Examples describe the preparation of (1) a mixture of ferric and cobaltous phosphates in a 3 : 1 molar ratio suported on silica gel, (3) a mixture of ferric and ceric pyrophosphates in a 4 : 1 molar ratio supported on silica gel, (6) a mixture of ferric and cupric pyrophosphates in a 1 : 1 molar ratio supported on silica, and (7) a mixture of ferric and cupric pyrophosphates in a 1 ¦ 1 molar ratio supported on pumice stone.
