Paragraph 0081-0082, (2021/08/11)
The invention belongs to wastewater treatment, and particularly discloses a high-value utilization method of sodium 2-mercaptoacetate in thionocarbamate production tail liquid. According to the method, sodium 2-mercaptoacetate in the thionocarbamate production tail liquid is used as a raw material and reacts with thiocyanate and a halogenating reagent to obtain the S-carboxyethyl-N-alkanoyl dithiocarbamate. The method is simple to operate and high in efficiency, solves the problem that the sodium 2-mercaptoacetate in the thionocarbamate production tail liquid is difficult to recover, and can realize high-value utilization of the sodium 2-mercaptoacetate.
