S>The thermal decomposition of the 5,7-dichloro-, 5,7dibromo- and 5,7- diiodo-8-quinolinol chelates of La, Ce, Pr, Nd, Sm, and Y was investigated on the thermobalance. The chelates decomposed in the temperature range from 65 to 125 deg C while the oxide levels were obtained from 395 to 805 deg C. Although the chelate thermal stability temperatures varied little with the chelating agent, the minimum oxide level temperatures were largely dependent on the halogen substitution on the 8-quinolinol molecule. Results of this study were correlated with previous studies on the rare earth metal chelates with 8-quinolinol and 2- methyl8-quinolinol. (auth)
