| titleOfInvention | The production method of thionyl chloride |
| abstract | The invention belongs to chemical production technical fields, and in particular to a kind of production method of thionyl chloride.The synthesis gas that sulphur and chlorine react generation in synthesis reactor enters reactor together with sulfur dioxide gas, directly enters decomposer behind absorption tower in the form of a vapor by the crude product thionyl chloride that reactor reaction generates；Rectifying column is entered by the gas phase crude product thionyl chloride that decomposer comes out, rectifying tower top gas phase enters return tank after condensing；Gas phase in return tank produces qualified products in recycled time synthesis reactor, rectifying column middle part after injector enters and evacuates tank.The present invention is due to converting heavy constituent for the light component in crude product thionyl chloride by the way of absorption tower, the pressure drop variation of conversion front and back is smaller, it is easily operated, easy to automate and make conversion more thorough by the way of tower, while greatly reducing the load of distillation system. |
