A method for preparing ethylenediamine by using ethanolamine and ammonia as raw materials. Apparatuses adopted in the method comprise a material heater, a reactor for ammonification reactions, a pressure reduction control valve, a gas-liquid separator, a distillation column for removal of the ammonia, a distillation column for ammonia stripping and a rectification column for ammonia recycling. Raw materials reacts in the presence of hydrogen, the reaction product mixture is subjected to the… CONTINUE READING
