Procedure

Hydrogen (10 ml/min) was passed through a saturator filled with propionitrile at 24° C., and the mixture was passed over the tungsten carbide catalyst at 150°-300° C. The catalyst that was prepared in Example 1 had been pretreated at 550° C. with hydrogen for fifteen hours. A mixture of propylamine, dipropylamine and tripropylamine was formed in the reactor, according to GC analysis. At temperatures above 250° C. formation of propane was also observed.
