ABSTRACT:
Organic hydrocarbons which comprise useful compounds may be obtained in a two-step process utilizing methane as a feedstock. The desired compounds are prepared by treating said methane with a halogenating agent such as chlorine, followed by contacting the methyl halide with a conversion catalyst comprising a silicalite. The silicalite which is employed is a silica polymorph consisting of crystalline silica which, after calcination in air at a temperature of 600.degree. C. for 1 hour, has a mean refractory index of 1.39.+-.0.01 and a specific gravity at 25.degree. C. of 1.70.+-.0.05 g/cc.
