| titleOfInvention | A kind of combined preparation method of morpholine and ethylene urea |
| abstract | The invention discloses a combined preparation method of morpholine and ethylene urea. After uniformly mixing 100 parts by weight of diethanolamine, 29-58 parts by weight of cyanuric chloride and 700-790 parts by weight of water, react at 85-95°C for 15 After ~16 hours, remove the water by distillation under reduced pressure, and dry the distillation residue to obtain a white solid; then place the white solid in an inert gas flow at 258-270°C and pyrolyze it to constant weight, and at the same time, discharge all the pyrolyzed particles discharged along the inert gas flow The gas is cooled, liquefied, concentrated and passed into fractionation equipment to fractionate the morpholine fraction at 128-129°C and the ethylene urea fraction at 258-265°C; finally purify the two fractions to obtain refined products of morpholine and ethylene urea respectively . The invention not only can jointly prepare morpholine and ethylene urea, and the total yield of the two can reach more than 50.6%, but also simultaneously obtain pyrolysis residue by-products with flame-retardant function, and the yield is 7.8-9.4%. |
