Vedclass · Answer

(A) Azeotropic distillation method: Rectified spirit $+$ Benzene $+$ water $\downarrow$ Fractional distillation The first fraction obtained at $331.8 \ K$ is a ternary azeotrope consisting of $H_2O$ $(7.4 \%)$,Benzene $(74 \%)$,and alcohol $(18.5 \%)$. The second fraction obtained at $341.2 \ K$ is a binary azeotrope consisting of Benzene $(67.7 \%)$ and alcohol $(32.2 \%)$. The final fraction obtained at $351 \ K$ is absolute alcohol.

When rectified spirit and benzene are distilled together,the first fraction obtained is
