A) A ternary azeotrope
B) Absolute alcohol
C) A binary azeotrope
D) Denatured spirit
Correct Answer: A
Solution :
Azeotropic distillation method ? Rectified spirit + Benzene + water ¯ Fractional distillation First fraction at 331.8 K is ternary azeotrope (\[{{H}_{2}}O\] 7.4% + Benzene 74% + alcohol 18.5%) Second fraction 341.2 K is a binary azeotrope (Benzene 67.7% + Alcohol 32.2%) Last fraction at 351K is absolute alcohol.You need to login to perform this action.
