Synthesis equipment of sodium thioglycolate

The utility model discloses synthesis equipment of sodium thioglycolate. A mixing reactor, three high-pressure reactors and a liquid inlet of a separation tower of the equipment are sequentially communicated, the three high-pressure reactors are sequentially communicated with the liquid inlet of the separation tower through overflow pipelines, an upper liquid phase outlet of the separation tower is communicated with a collection tank, and a lower liquid phase outlet of the separation tower is communicated with a finished product tank. A gas phase outlet of the separation tower is communicated with the alkali absorption device, and the collection tank is communicated with the mixing reactor; the mixing reactor is provided with a cooling mechanism, each of the three high-pressure reactors is provided with an automatic pressure release valve, a temperature control mechanism and a stirring mechanism, and a freezing heat exchanger is arranged at the top of the high-pressure reactor communicated with the mixing rea
