>A silver(I)-manganese(II) catalyst system markedly increases the rate of oxidation of glycerol, erythritol, pentaerythritol, and 8-quinolinol by cerium(N) sulfate in perchloric acid. Complete reaction requires only 3 to 5 minutes at 90 deg C, the end point being indicated by formation of the red color of permanganate. Glycerol (3 to 50 mg.), erythritol, or pentaerythritol (3 to 16 mg.) may be determined with a standard deviation of 0.3 to 0.5%; gallium(III), indium(III), aluminum(III), or magnesium(II) (0.05 to 5.0 mg.) may be determined after dissolution of the 8-quinolinol precipitates with a standard deviation of 1.0%.
