Abstract: Aiming at traditional high production cost, intractable production process, a new technology of synthesis for ethyl thioglycolate was put forward, using ethyl chloride, xanthate, and monoethylamine as raw material. The results showed that: with ethyl chloride, xanthate, monoethylamine dosage of 1〖DK（〗∶〖DK）〗0.98〖DK（〗∶〖DK）〗1.10, esterification temperature at 60 ℃, amination temperature at 40 ℃, ethyl thioglycolate was synthesized, which has good performance in collecting sulfide minerals, and can be used as collectors for sulfide minerals flotation.

Key words: thyl thioglycolate, Collector, Synthesis cogeneration
