PROCESS FOR THE PREPARATION OF PIPERAZINE-N-DITHIOCARBAMIC ACID

摘要

This compound finds application as an anthelmintic agent, an accelerator in the vulcanization of rubber products and in the analytical chemistry. This zero-discharge method permits isolating a quantitative yield product while making use of a low toxicity solvent with no need for using auxiliary reagents and no energy consumption for solvent regeneration and wastewater purification. The method comprises reacting carbon disulphide with non-aqueous piperazine in an ethyl alcohol medium at temperatures 20-60 degrees C.
