| titleOfInvention | For loaded catalyst prepared by 1,2 propane diamine |
| abstract | The invention discloses a class loaded catalyst, 1,2 propane diamine are prepared with this catalyst, its central synthetic steps is as follows：Add 1,2 dichloropropanes, ammoniacal liquor, loaded catalyst, reactor at the uniform velocity to be rotated in homogeneous reactor in a kettle., aminating reaction is carried out at 140 DEG C~170 DEG C of reaction temperature and prepares 1,2 propane diamine, the yield of product is higher than 65%.After reaction terminates, unreacted ammonia is removed first, then air-distillation obtains the aqueous solution of 1,2 propane diamine.Advantages of the present invention：(1) loaded catalyst catalysis prepares 1,2 propane diamine, obtains yield higher；(2) it is raw material using the dichloropropane of accessory substance 1,2 produced during production chloropropene, production cost greatly reduces；(3) course of reaction is simple, easy to operate；(4) this method safety and environmental protection, beneficial to industrialized production. |
