“…In contrast, almost all of the complex on Ti02-300-200 was extracted with benzene. 2 The major portion of CoTPP on TiO2-120s was, thus, converted to be insoluble in benzene but soluble in quinoline during the evacuation at 250 °C. The atomic ratios and molecular weights of CoTPP and the benzene, pyridine, and quinoline extracts are summarized in Table V.…”
