Cafissi, S. Beduschi, V. Balacco, B. Sacchi, S. Trasatti] We studied the chemical dechlorination of the polychlorinated biphenyls (PCBs) in some dielectric oils via nucleophilic substitution of the chloro atoms by polyethylene alkoxide. The influence of temperature, ultrasounds, polyethylene glycol (PEG) and base type was investigated. Our findings show that dechlorination of PCBs by chemical treatment is effective at moderate temperature (90-100°C) and is strongly dependent on the nature of matrix oil. Stirring affects the process yield by influencing the homogeneity of the oil/glycol two-phase system. Ultrasounds can improve the process efficiency by making operating conditions less severe.
