摘要 在116~234℃范围内用饱和气流法测定了工业黄磷的磷蒸气压,并拟合得到磷蒸气压方程:lnPvr= - 0.845994- [7.018404(1- Tr )1.5 - 0.964256(1- Tr )6 ]/Tr, 其平均绝对相对误差为0.55% ,最大相对误差为1.05% 。用它导出的磷气化热计算式与文献报导的计算结果极一致。 The phosphorus vapor pressures of liquid industrial yellow phosphorus were measured by the saturated gas current in the range of temperature 116 to 234℃.The data were fitted with the equation: ln P vr =-0.845994-[7.018404(1-T r ) 1.5 -0.964256(1-T r ) 61/T r Where, P vr was the reduced vapor pressure; T r was the reduced temperature. Its mean absolute relative error was 0.55%, and the maximal value was 1.05%. Using this equation, the formula for heat of vaporization was inferred:ΔH v =RT c [10.527606(1-T r) 0.5 -3.509202(1-T r ) 1.5 -5.785536(1-T r ) 5+4.62128(1-T r ) 6], R was the universal gas constant.Its computed values were very identical with the results of the formula for liquid yellow phosphorus reported in the literature.
