Notes:
Abstract T-zeolites with different H+-exchange degrees (0, 44, 68 and 89%) were used for the amination of dimethyl ether in the temperature range of 603 to 703 K. On a Na, K-T-zeolite sample (synthesis form) at low dimethyl ether conversion high selectivities of lower methylated amines were observed and methanol was formed as by-product. By proton exchange the conversion could be enlarged, but the selectivity distribution was shifted to trimethylamine.
