Production process for preparing insoluble sulphur through low temperature method



The present invention relates to a production process for preparing insoluble sulphur through a low temperature method, wherein ordinary industrial sulphur is adopted as a raw material, heating liquefaction, polymerization reaction, quenching, drying, crushing, extraction and oil filling are sequentially performed, the polymerization reaction is performed at a temperature of 220-300 DEG C, and stabilizers are respectively added during the polymerization reaction stage, the quenching stage, and the oil filling stage, such that the prepared insoluble sulphur has high thermal stability and high content. The process for producing the insoluble sulphur has advantages of low production equipment investment, simple process, low energy consumption, and the like.
