摘要： A process for reforming alkyleneamines to predominantly linearly-extended polyalkylenepolyamines comprising contacting an alkyleneamine or mixture thereof with a catalyst under conditions such that a mixture of polyalkylenepolyamines enriched in linearly-extended products is formed, said catalyst containing at least one compound selected from the group consisting of (a) Group VB metal oxides, (b) Group VB metal phosphates, (c) silicates of Groups IIA, IIIB, IVB, VB, and the lanthanide and actinide metals, and (d) tungsten oxdies, with the proviso that the silicates and tungsten oxides are essentially free of aluminum. For example, ethylenediamine is contacted with a catalyst of niobium phosphate or niobic acid under reaction conditions to yield predominantly non-cyclic polyethylenepolyamines.

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.
