Abstract: The vapor pressure of iso-PrCl was measured in the range -1.80 to 39.00° and of allyl chloride (I) from 3.27 to 47.32°. The vapor pressure can be calcd. by the least-squares method with equation for iso-PrCl: log P°(mm) = 6.6452 - [947.54/(216.62 + t)] with a relative standard error of the estimate ±0.2% and for I: log P°(mm) = 6.6562 - [956.99/(208.60 + t)] with an error of ±0.1%. The isobaric equil. of the liquid-vapor system of iso-PrCl (1) and I (2) was measured and the relative volatility can be expressed by the equation: α = (1 + 2.3715 x1)/(0.6637 + 1.8147x1) with an error ±0.0015, where α indicates the relative volatility y1x2/y2x1 with xi (i = 1,2) as a mole fraction of liquid components and yi as a mole fraction of gaseous components. Exptl. results are thermodynamically consistent and the system is almost ideal.
