| titleOfInvention | Liquid ammonia process for caustic soda purification produces ethylenediamine technique |
| abstract | The present invention relates to liquid ammonia process for caustic soda purification to produce ethylenediamine technique.Catalytic ammoniation reaction product is by recycling ammonia in the present invention, after azeotropic distillation removes free water and the crystallization water, mixture containing ethanol amine is by the isolated ethylenediamine of multiple rectifying columns (EDA), piperazine (PIP), diethylenetriamine (DETA), triethylene diamine (TEDA), heavy constituent (aminoethyl ethanolamine (AEEA), aminoethyl piperazine (AEP), mixed amine and the oligomer such as hydroxyethyl piperazine (HEP)), separating and recovering unreacted ethanol amine (MEA) is recycled to ammoniation reactor simultaneously, can be used in the technique productions of ethylenediamine. |
