A Study has been made of the nonaqueous extraction of zinc from hydrogen chloride solution of diethylene glycol with TOPO in decaline. Zinc ion was extracted at three different hydrogen chloride regions. The first extraction occurred in the neutral region of pCH. The second appeared between 4 x 10-5 and 4 x 10-2 M HC1, and the extracted species was found to be ZnC12•2TOPO. The third showed a maximum distribution at 0.4 M HC1, and the species was mainly attributable to the extrac-tion of HZnCI3•4TOPO. KEY WORDS: Nonaqueous extraction / Zinc chloride / Diethylene glycol
