三元可燃性液体水溶液闪点的理论预测

摘要

To predict flash points of ternary organic-water solution mixtures main factors, such as boiling point, molecular mass, relative density, saturated vapor pressure, surface tension, etc. As input parameters were analyzed. The relationship between these parameters and the flash points of solution mixtures was investigated by using the support vector machine. The flash point prediction model of ternary organic-water solution mixture was established. The validity and the reliability were discussed.%为了预测三元互溶可燃性液体水溶液的闪点,分析确定了影响混合溶液闪点的主要因素,如沸点、相对分子质量、相对密度、饱和蒸汽压、表面张力等.将这些因素作为输入变量,应用支持向量机算法对混合溶液闪点与其对应理化参数之间的内在定量相关性进行了研究,建立了三元互溶可燃性液体水溶液闪点的理论预测模型.对预测模型进行了验证,讨论了模型的有效性和可靠性；解释了模型反映的机制,明确了混合溶液闪点的主要影响因素及其重要程度.
