Abstract:
A novel extraction procedure has been developed for treating phenolic wastewater. Alcohols, amines, and organic acids were applied as extractants in separation of phenol from the wastewater containing 6000 mg/l phenol and 5% salts discharged by chemical plants, >99% phenol was recovered by extracting with octanol. The interactions of phenol with alcohols, amines, and organic acids were studied by a theoretical calculation with GAUSSIAN 98. The extraction efficiency is strongly dependent on the intermolecular interactions between the phenol and extractants. Based on the experimental and theoretical studies, a pilot-scale LLES was set-up and worked well.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
