Abstract
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.
Claims32
A process of converting a methane or a methane containing natural gas to a monohalogenated methane comprising going through a methanesulfonyl halide as an intermediate and allowing the methanesulfonyl halide to decompose under a substantially anhydrous condition, forming also a hydrogen halide and a sulfur dioxide in the process of conversion and decomposition.
A process of producing a monohalogenated methane from a methane or a methane containing natural gas, through a methanesulfonyl halide as an intermediate, comprising the steps of:
- a) reacting the methane with a sulfur dioxide and a halogen, with the sulfur dioxide, a hydrogen halide, and an oxidant, or with a sulfuryl halide, to form the methanesulfonyl halide and a hydrogen halide;
- b) contacting the methanesulfonyl halide with a catalyst complex to form the monohalogenated methane and a sulfur dioxide under a reaction condition that is substantially anhydrous.
A composition comprising:
- a methane or a methane containing gas, and
- a sulfur dioxide and a halogen;
- the sulfur dioxide, a hydrogen halide, and an oxidant;
- or a sulfuryl halide, whereby the methane reacts with the other species under a substantially anhydrous condition to form a monohalogenated methane,
- a hydrogen halide, and a sulfur dioxide, via a methanesulfonyl halide intermediate.
