<p>In the catalytic preparation of methylamines from methanol and ammonia using an aluminosilicate catalyst, the mono-, di- and trimethylamine content of the product mixture can be varied from the equilibrium mixture ordinarily produced by using an amorphous aluminosilicate catalyst containing varying amounts of sodium, potassium, lithium, barium or strontium atoms as a result of treating an amorphous aluminosilicate with a corresponding metal hydroxide.</p> |
