A process for preparing triethylenediamine such thatndiethanolamine as a starting material is subjected tondecomposition in liquid phasenat temperatures of 220 to 330 ° C, optionally in the presencensolvents with a higher boiling pointnthan 250 "C, such as terphenyl or diphenyl oxide,nin an amount of 1- to 5 times the defaultndiethanolamine and in the presence of mono- orndicarboixyl acids such as acetic acidnor · succinic, as a catalyst. Triethylenediaminenis used as a catalystnfor polyurethane foams |
