In previous papers (1, 2) it has been shown that in dilute aqueous solutions aldehydes may be oxidized in the a! position by oxidizing agents such as ceric sulfate, potassium dichromate, and potassium ferricyanide. Normal butyraldehyde and isobutyraldehyde yielded the most conclusive results; the latt,er was converted by ceric sulfate at 80’ into cr-hydroxyisobutyraldehyde and acetone. The evol...

Different chemical formulations for the synthesis of highly intercalated graphite bisulfate have been tested. In particular, nitric acid, potassium nitrate, potassium dichromate, potassium permanganate, sodium periodate, sodium chlorate, and hydrogen peroxide have been used in this synthesis scheme as the auxiliary reagent (oxidizing agent). In order to evaluate the presence of delamination, an...
