    • 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.
    • 本发明涉及通过甲醇和/或二甲醚与氨的催化反应以及含甲胺原料的催化重整制备甲胺的非平衡分布的方法。 在甲醇或二甲醚的高转化率下,一种方法选择性地提供富含单胺和二甲胺和低三甲胺的反应产物。 重整含有甲胺的原料,任选地在催化剂上含有氨的工艺效果的变化。 在高转化率下实现这种低TMA选择性的关键在于使用微孔沸石,优选菱沸石,几何选择性指数(GSI)小于约3,形状选择性指数(SSI)大于约5的催化剂和吸附 1-PrOH的容量至少为0.5mmol / g。
