ES2243380T3 PROCEDIMIENTO PARA LA OBTENCION DE TRIETILENDIAMINA (TEDA). 未知

PROCEDIMIENTO PARA LA OBTENCION DE TRIETILENDIAMINA (TEDA).
Abstract:
Procedimiento para la obtención de trietilendiamina (TEDA) mediante reacción de etilendiamina (EDA) en presencia de un catalizador de zeolita, caracterizado porque el catalizador de zeolita presenta una proporción molar SiO2 / Al2O3 mayor que 1400 : 1, y la temperatura de reacción asciende a 250 a 500ºC.
Abstract(English):

Preparation of triethylenediamine (I, 1,4-diazabicyclo(2,2,2)octane) by reacting ethylenediamine (II) at 250-500degreesC in presence of a zeolite catalyst (A) containing at least one metal (M) in oxidation states II, III or IV, as the oxide. Preparation of triethylenediamine (I, 1,4-diazabicyclo(2,2,2)octane) by reacting ethylenediamine (II) at 250-500degreesC in presence of a zeolite catalyst (A) containing at least one metal (M) in oxidation states II, III or IV, as the oxide. When M is aluminum, the SiO2:M oxide mole ratio is over 1400:1, when M has an oxidation state II or III the mole ratio is over 100:1, and when M has an oxidation state IV, the mole ratio is over 10:1.
