Q.1. The feed stream containing 25% acetic acid (A) and 75% chloroform (B) by mass is fed to a counter- current extraction system and pure water (C) is used as solvent. At the end of the extraction process, acetic acid is obtained as 5% by mass in raffinate phase. The extract stream is sent to a separator to separate all the water and then the remaining extract contains 85% acetic acid. E1 EN S-EN 1 E. h F-R.
