AMINES CATALYSIS USING METALLIC POLYPHOSPHATE CONDENSATION CATALYSTS HAVING A CONDENSED STRUCTURE

摘要

This invention relates to a process for making amines by condensing an amino compound in the presence of a metallic polyphosphate condensation catalyst having a condensed structrue. This invention also relates to an alkyleneamines producers composition rich in triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and penta-ethylenehexamine (PEHA).
