摘　　要：采用低温熔融法制备不溶性硫磺,考察升温速率对不溶性硫磺转化率和热稳定性的影响。结果表明,最佳升温速率为4℃/min。在最佳升温速率下,不溶性硫磺的转化率为42.86%,热稳定性分别为86.02%(105℃/15 min)和43%(120℃/15 min),熔点为124.04℃。Insoluble sulfur was prepared by low temperature melting method .The influence of heating rate on the conversion and thermal stability of insoluble sulfur was investigated .The results showed that the op-timal heating rate was determined to 4 ℃/min,the conversion rate was 42.86%,thermal stabilities were 86.02%（105 ℃/15 min） and 43% （120 ℃/15 min）,respectively.The melting point of the sample was determined to 124.04 ℃.
