Paragraph 0025; 0026; 0027; 0031-0036, (2017/05/12)
The invention discloses a dimethylamine wastewater recycling method. The method comprises the following steps that dimethylamine wastewater in industrial production is subjected to rectification operation, a dimethylamine water solution with the mass percentage being 5-50% is obtained, and then the dimethylamine water solution and cyanamide are subjected to an addition reaction with the existence of sulfuric acid to obtain metformin sulfate. According to the method, dimethylamine is recycled, the problem that environment is polluted by dimethylamine wastewater in organic chemical production such as pesticide, medicine, rubber and leather is solved, joint production can be achieved by means of the method, and economic benefits can be improved.
