  • Patent number: 5399769
    Abstract: This invention relates to a process for producing a nonequilibrium distribution of methylamines by the catalyzed reaction of methanol and/or dimethyl ether with ammonia and by the catalytic reforming of a methylamine containing feedstock. One process selectively affords a reaction product enriched in mono and dimethylamines and low in trimethylamine, at high conversion of methanol or dimethylether. A variation of the process effects reforming a methylamine containing feedstock, optionally containing ammonia over a catalyst. The key to achieving this low TMA selectivity at high conversion resides in the use of a microporous zeolite, preferably chabazite, catalyst having a geometric selectivity index (GSI) less about 3, a shape selectivity index (SSI) greater than about 5 and a sorption capacity for 1-PrOH of at least 0.5 mmol/g.
