Separation of acetone from water by using MIBK.
A stream containing 30 wt% acetone and the balance water is to be separated by extraction with methyl isobutyl ketone. 100 kg of the acetone-containing stream is to be mixed with pure MIBK and the mixture allowed to settle and separate. How much MIBK must be used if the final acetone concentration in the water-rich phase is 5 wt%?
Mass of MIBK used = ________kg
