Title:
ハロゲン化C1炭化水素を生成させるC1炭化水素の酸化的ハロゲン化およびこれに関連する統合されたプロセス
Document Type and Number:
Japanese Patent JP4226910
Kind Code:
B2
Abstract:
An oxidative halogenation process involving contacting a reactant hydrocarbon selected from methane, a halogenated C1 hydrocarbon, or a mixture thereof with a source of halogen and, preferably, a source of oxygen in the presence of a rare earth halide or rare earth oxyhalide catalyst, so as to form a halogenated C1 hydrocarbon having a greater number of halogen substituents as compared with the reactant hydrocarbon. Preferably, the product is a monohalogenated methane, more preferably, methyl chloride. The oxidative halogenation process to form methyl halide can be integrated with downstream processes to produce valuable commodity chemicals, for example, methyl alcohol and/or dimethyl ether; light olefins, including ethylene, propylene, and butenes; higher hydrocarbons, including gasolines; vinyl halide monomer, and acetic acid. Hydrogen halide, which is a co-product of these downstream processes, can be recycled to the oxidative halogenation process.
