Hi, the given question is incomplete, the complete question is:
You carry out a reaction that yields a major product Q (boiling point: 120°C) and side product R (boiling point: 150°C). The ratio of Q to R is 70:30. Both Q and Rare liquids.
After the ethyl acetate is evaporated, Q and R (a mixture of liquids) remain. What criteria does this mixture have to satisfy to be separated by simple or fractional distillation (besides bp difference and composition)?
Answer:
The basic criteria are that the two liquids should be miscible. A mixture of two miscible liquids is further separated by the process of simple distillation and fractional distillation. For the liquids that exhibit varied boiling points, with a difference of +30 degrees C, the process of simple distillation is used. On the other hand, for the liquids whose boiling points come between the range of o to 30 degrees C, the process of fractional distillation is used.
