Abstract
A process for making methyl iodide is disclosed. In this process methane, and a source of oxygen are introduced into a molten salt, maintained at a temperature of at least about 500.degree. C., said molten salt comprising an iodide of a metal selected from the group consisting of alkali metals, alkaline earth metals and mixtures thereof and a catalyst comprising at least one metal selected from the group consisting of a metal of Group IB and Group VIII of the Periodic Table of the Elements with the proviso that said methane and said source of oxygen do not contact each other.
Claims27
A process for making methyl iodide from methane comprising introducing methane and a source of oxygen into a molten salt, maintained at a temperature in the range of between about 500.degree. C. and below about 675.degree. C., comprising an iodide of a metal selected from the group consisting of alkali metals, alkaline earth metals and mixtures thereof and a catalyst comprising at least one metal selected from the group consisting of metals of Group IB and Group VIII of the Periodic Table of the Elements with the proviso that said methane and said source of oxygen not contact each other.
A process for making methyl iodide from methane comprising introducing methane, a source of oxygen, and steam into a molten salt, maintained at a temperature at or above about 675.degree. C., said molten salt comprising an iodide of a metal selected from the group consisting of alkali metals, alkaline earth metals and mixtures thereof and a catalyst comprising at least one metal selected from the group consisting of metals of Group IB and Group VIII of the Periodic Table of the Elements with the proviso that said methane and said source of oxygen do not contact each other.
A process for making methyl iodide from methane comprising introducing methane, oxygen, steam and hydrogen iodide into a molten salt, maintained at a temperature in the range of between about 500.degree. C. and about 750.degree. C., said molten salt comprising lithium iodide and lithium hydroxide and a ruthenium-containing catalyst with the proviso that said methane and said oxygen do not contact each other.
