Abstract
This invention relates to a process for making amines by condensing an amino compound in the presence of a condensation catalyst and a condensation catalyst promoter, wherein said condensation catalyst promoter is present in an amount sufficient to promote the condensation catalyst. This invention also relates to an alkyleneamines producers composition rich in triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and pentaethylenehexamine (PEHA).
