    • 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.
    • 一种将亚烷基胺重整为线性延伸的聚亚烷基多胺的方法,包括在形成富含线性延伸产物的多亚烷基多胺的混合物的条件下使亚烷基胺或其混合物与催化剂接触,所述催化剂含有至少一种选自以下的化合物: (a)VB族金属氧化物,(b)VB族金属磷酸盐,(c)IIA,IIIB,IVB,VB族和镧系元素和锕系金属的硅酸盐,(d)钨氧化物,条件是 硅酸盐和钨氧化物基本上不含铝。 例如,乙二胺在反应条件下与磷酸铌或铌酸的催化剂接触,主要产生非环状聚亚乙基多胺。
