- Acetate is to be extracted from a feed mixture of 30wt% acetone and 70wt% ethyl acetate using pure water at 30C. The extraction process yields the following data, A. Calculate the extraction stages for this process? B. Define the wt. % of the raffinate if the wt.\% of the extract at the same point was 0.7 wt. %? - Acetate is to be extracted from a feed mixture of 30wt% acetone and 70wt% ethyl acetate using pure water at 30C.
