      摘要: A process of reforming an alkyleneamine feedstock or a mixture of such feedstocks to an alkyleneamine or a mixture of alkyleneamines which is different from the feedstock or feedstock mixture. The process is catalyzed by one of the following: Group VB metal oxides, Group VB metal phosphates, Group IIA metal silicates, and tungsten oxides. For example, ethylenediamine is contacted with a catalyst of niobic acid or magnesium silicate to yield predominantly diethylenetriamine and non-cyclic triethylenetetramines; whereas high molecular weight polyethylenepolyamines are cracked by the same catalysts to mixtures of lower molecular weight linear and cyclic materials.

      摘要: An improved process for the preparation of triethylamine by gas phase catalytic hydrogenation of acetonitrile is disclosed, the improvement residing in employing as the catalyst a supported noble metal of Group VIII of the periodic system catalyst where the support comprises lithium aluminum spinel. The process can be carried out in the presence of up to 5% by weight of monoethylamine and/or diethylamine. The process is conducted at 80.degree.-115.degree. C. and under a pressure of 1 to 60 bars.

      摘要: A trialkylamine is prepared by contacting a dialkylamine with a liquid reaction medium containing a ruthenium, osmium, rhenium or technetium metal catalyst, preferably in complex association with a biphyllic ligand at a temperature of 50*-400* C. A typical reaction comprises contacting dibutylamine with ruthenium trichloride and triphenylphosphine to produce tributylamine and butylamine.
