Abstract: Liquid-liquid extraction is a unit operation and it is a process of transferring a solute from one liquid phase to another immiscible or partially miscible liquid in contact with the first. The liquid- liquid extraction of O-Cresol and Water mixture (38.1% O- Cresol, 61.9% water) is carried out by using Ethylene Dichloride as a solvent. Liquid-liquid extraction is a method to achieve high recovery of solute with good selectivity in recovery of O-cresol from O-cresol and water mixture. The liquid- liquid extraction efficiency is calculated in terms of KD and degree of extraction. In liquid-liquid extraction, chemical equilibrium experiments are carried to calculate the number of stages required to recover high purity and yield of O-Cresol by using Ethylene Dichloride. It was found that the rate of extraction increase with increases in the solvent to feed ratio. By using this process 99% pure O-Cresol from the bottom of distillation column can be obtained.This O-cresol can be used as a raw material for producing DMBPC & this will also helpful in minimizing water pollution & Also energy conservation.
