| titleOfInvention | A method of preparing butanediamine |
| abstract | The invention discloses a kind of methods preparing butanediamine, it is to obtain butanediamine by dehydration and hydrogenation reaction using ammonium succinate as raw material.Simultaneously, preparation method above-mentioned can also be combined with the bacterial strain for being resistant to high concentration ammonium ion and high-yield succinic, succinic acid ammonium salt is prepared by anaerobic fermentation, and then its clear aqueous solution is obtained with decolorization under conditions of non-purifies and separates by being simply separated by solid-liquid separation, ethylenediamine is prepared, provides a kind of method that bioid prepares ethylenediamine.Compared with prior art, process of the present invention is simple, and efficiency and yield are high.Meanwhile whole process is using renewable biomass resources as raw material, and each process is relatively simple and can implement, and has great social effect and economic value. |
