    摘要: Hydrocarbons and other compounds are halogenated to halocarbon products by contact with a halocarbon in the presence of an acidic zeolite catalyst such as ZSM-5. The process is particularly useful for the halogenation of methane to form chemicals of higher value.

    摘要: Alpha-picolines are produced by containing aniline or substituted anilines, such as alkyl-, cyclo alkyl-, halo- ; alkoxy- or substituted alkyl-anilines with a crystalline zeolite catalyst having a silica:alumina ratio of at least 12 and a constraint index of 1 to 12. ZSM-5 type catalysts are contacted at elevated temperature to yield alpha-picolines selectively.

    摘要: Alpha-picoline is produced by the ammoniation of phenol over a zeolite having a silica:alumina ratio of at least 12 and a constraint index of 1 to 12. The preferred zeolite is ZSM-5. Aniline is produced as a co-product and the alpha-picoline may be separated by distillation or extraction.

    摘要: The invention deals with a process for making a pyrazine from an aminoalkanol by passing it over a crystalline aluminosilicate zeolite having a silica to alumina ratio of at least 12 and a constraint index of 1 to 12 under conditions to dehydrate, dehydrogenate and cyclize it.
