Production process of sulfoxide chloride

[0019] Example 1

[0020] (1) The synthesis gas produced by the reaction of sulfur and chlorine in the synthesis kettle enters the reactor together with sulfur dioxide gas, and the crude thionyl chloride generated by the reaction in the reactor is directly decolorized in the gaseous form through the sulfur tank and then enters the decomposer, the sulfur tank The bottom liquid phase is recycled to the synthesis kettle;

[0021] (2) The crude gas phase thionyl chloride from the decomposer enters the rectification tower, and the heavy components produced at the bottom of the rectification tower are recycled back to the synthesis kettle. The gas phase at the top of the rectification tower enters the reflux tank after condensation, and part of the liquid in the reflux tank The phase is pumped by the first machine to the rectification tower to reflux, and the remaining liquid phase in the reflux tank is recovered and reused in the synthesis kettle; the volume ratio of part of the liquid pha

[0028] (1) The synthesis gas produced by the reaction of sulfur and chlorine in the synthesis kettle enters the reactor together with sulfur dioxide gas, and the crude thionyl chloride generated by the reaction in the reactor is directly decolorized in the gaseous form through the sulfur tank and then enters the decomposer, the sulfur tank The bottom liquid phase is recycled to the synthesis kettle;

[0029] (2) The crude gas phase thionyl chloride from the decomposer enters the rectification tower, and the heavy components produced at the bottom of the rectification tower are recycled back to the synthesis kettle. The gas phase at the top of the rectification tower enters the reflux tank after condensation, and part of the liquid in the reflux tank The phase is pumped by the first machine to the rectification tower to reflux, and the remaining liquid phase in the reflux tank is extracted and reused in the synthesis kettle; the volume ratio of part of the liquid pha
