| titleOfInvention | A kind of technique preparing thiocarbamide |
| abstract | The invention belongs to technical field of organic synthesis, and in particular to a kind of technique for preparing thiocarbamide adds dehydrating agent using urea and NaHS as raw material, and reaction is made in organic solvent.Solvent of the present invention may be recovered recycling, easy to operate.Hydrogen sulfide is replaced using NaHS during the reaction, reduces monitoring and the hydrogen sulfide gas quantitative problem of flowmeter；No three wastes generates in entire reaction process, environmentally protective.Products obtained therefrom high income, production cost is low, is more advantageous to industrialized production. |
