摘要：
Proces for producing dimethylamine by passing monomethylamine over a crystalline aluminosilicate catalyst selected from
a) mordenite wherein the primary cation is Na, HNa having at least 2 % Na, Mg, Ca, Sr or Ba
b) ferrierite wherein the primary metal cation is Na, K, Mg, Ca, Sr or Ba
c) clinoptilolite and
d) phillipsite,
at a temperature of 250-475°C and a pressure of 7-7000 kPa, at a feed rate of 0.1-10 g of monomethylamine/g of catalyst per hour, at a monomethylamine conversion of 15-75% Selectivity is normally in excess of 80%.
