Solvents were classified for their ability to dissolve phenols and were compared with experimental data of the literature in order to observe if the solvent extraction of phenols in practice matches with the authors theoretical approach. Results indicated the superiority of alcohols and acetone for the recovery of phenols in line with experimental data of previous studies. Furthermore, activity coefficients values were found to increase with the increase of temperature. This study provided a knowledge base for the selection of the most appropriate solvents for a given phenolic compound||URI:||http://ktisis.cut.ac.cy/handle/10488/6558||ISSN:||10942912||DOI:||10.1080/10942912.2010.522750||Rights:||Copyright © Taylor & Francis Group, LLC||Type:||Article|
