| titleOfInvention | Remove the method and its device of the impurity sulfur dichloride in thionyl chloride |
| abstract | The invention belongs to chemical production technical field, and in particular to a kind of method and its device for removing the impurity sulfur dichloride in thionyl chloride.Methods described is：Enter over cure tank after the thionyl chloride gas heating containing sulfur dichloride 1~3% steamed at the top of rectifying column to react, described device includes crude product receiving tank, crude product receiving tank, with being sequentially connected with sulphur tank, rectifying column, heater, over cure tank, molten sulfur line is set with sulphur tank top by pipeline.1~3% sulfur dichloride contained in thionyl chloride can be reduced to less than 0.004% by the present invention, reach the requirement of high-class product 1# colors in professional standard；Solve the problem of over cure pot bottom line clogging, realize continuous production. |
