“…
The absorbance spectrum was examined in the range 300 to 550 µ. The spectrum obtained is similar to that obtained by Stiller (8) showing the same two inflections between 350 to 400 µ and 450 to 485 µ. This indicates that the compound formed between isopropyl alcohol and vanadium oxinate is of the same nature as tha'; of the other alcohols.When measured at 380 µ, the absorbances shown in Table I were obtained with the standard isopropyl alcohol solutions.Addition of Lithium Sulfate.
