Tripropylamine - Preparation Method
Open Data Verified Data
with N-propanol as raw material under the action of Ni-CLi-Al2 03 catalyst, dehydrogenation generates propanal, and then with ammonia addition, dehydration, hydrogenation to produce propylamine, and then by repeated dehydration, hydrogenation to produce dipropylamine and tripropylamine. The reaction temperature was (210±10)℃, the pressure was 396. 66kPa, and the space velocity of N-propanol was 0. 25-0.51L/L.h-I. The raw material ratio is alcohol: Ammonia: hydrogen -4:2:4. The conversion of N-propanol is 75% ~ 83%, and the total yield of di-and tripropylamine is 75% ~ 80%, in which dipropylamine is 37% ~ 41% and tripropylamine is 35% ~ 40%.
