| Abstract: | The technology of producing insoluble sulfur by low temperature melt is presented. The effects of technical parameters on the thermal stability at 120℃ of insoluble sulfur are studied. The optimal technical parameters are determined as follows： reaction temperature is 240 ℃, the mass fraction of stabilizer is 0. 05%. Under the optimal conditions, the thermal stability at 120 ℃of insoluble sulfur is up to 50%. |
