Abstract
for Processes for converting a methane or a methane containing natural gas to a monohalogenated methane and other downstream basic commodity chemicals going through methanesulfonyl halide as a key intermediate, whereby following its formation, the methanesulfonyl halide is allowed to decompose under a substantially anhydrous condition, preferably in the presence of a catalyst complex, and whereby in addition to the monohalogenated halide, a hydrogen halide and a sulfur dioxide are also formed in the overall conversion, both of which may be recycled back to the beginning of the processes. Additionally, compositions utilizing such a key intermediate for the same purposes are also disclosed.
Claims12
A process of converting a methane containing gas to a monohalogenated methane comprising traversing a reaction pathway wherein a methanesulfonyl halide is formed as an intermediate and decomposes under a substantially anhydrous condition, and wherein the methanesulfonyl halide decomposes in the presence of a catalyst complex that is at least one of an ionic liquid or a conjugate base of a nitrogen containing cation of said ionic liquid.
A process of producing a monohalogenated methane from a methane containing gas through a methanesulfonyl halide intermediate, comprising:
- a) reacting the gas to form the methanesulfonyl halide intermediate;
- and
- b) contacting the methanesulfonyl halide intermediate with a catalyst complex to form the monohalogenated methane under a reaction condition that is substantially anhydrous, wherein the catalyst complex is at least one of an ionic liquid or a conjugate base of a nitrogen containing cation of said ionic liquid.
