For the 6 binary systems of chloroform with acetone, 2-butanone, ethyl formate, methyl acetate, ethyl acetate, and vinyl acetate, we measured azeotropic temperatures and compositions at low pressure range (400㎜Hg-800㎜Hg). And at each pressures, we calculated the azeotropic points by using UNIFAC equation. The azeotropic points obtained from experiment and calculation were comparativety identified. By ploting pressure vs. azeotropic points, we could get an equation, ln T_(az)=A+B ln P, and azeotropic compositions changed linearly with pressures.
