推算有机卤代烃饱和蒸气粘度的新方法

Method for Calculating Viscosity of Halide at Saturated Vapor State

在大量数据评估和分析的基础上，提出了一种推算有机卤代烃饱和蒸气粘度的新方法．该方法在已知物质的临界温度、临界压力、临界比容、分子质量和偏心因子的情况下，可以计算有机卤代烃的饱和蒸气的粘度，该方法适用的对比温度范围为０．５０～０．９５．用该方法推算所得的饱和蒸气的粘度平均偏差不超过±５％。

Available data are used to calculate the viscosity of halide at saturated vapor state. The predicting method adopts following thermophysical properties: critical temperature,critical pressure, critical special specific volume, molecular weight and the eccentric factor. The valid range of reduced temperature is from 0.5 to 0.95.The deviation for the saturated vapor is not more than ±5%,which meets the requirement for engineering application.
