Abstract
Inventia se refera la un procedeu de preparare, a trietilendiaminei, în care N, N'-dihidroxietilpiperizina se ciclizeaza în faza gazoasa pe un catalizator de alumina alcalinizat cu o baza aleasa dintre hidroxizi alcalini sau alcalino-pamîntosi în proportie de 0,01...10% de alumina la o temperatura de reactie între 200...550 degree C, de preferinta 300...450 degree , încarcarea catalizatorului fiind între 0,1...10 kg N, N' dihidroxietil-piperazina/kg catalizator/h, iar presiunea de lucru între 0,1 si 10 at.
