Abstract
This invention relates to a process for making amines having a high yield weight percent of linear triethylenetetramine (L-TETA) and aminoethylethanolamine (AEEA) by condensing an amino compound in the presence of a condensation catalyst selected from a Group IVB metal oxide, a Group VIB metal-containing substance and a promoted condensation catalyst. This invention also relates to an alkyleneamines producers composition rich in L-TETA and AEEA.
