| Abstract: | The selective synthesis of dimethylamine from ammonia and methanoi have been studied over the steam treated mordenites. It has been shown that the activity of such catalyst is enhanced ,the conversion of methanol is above 90%,the yield of dimethylamine reach 70%, while the yield of trimethylamine is below 5%. The acid characteristic of such improved catalyst was explained with the help of IR studies. |
