were studied after oral admin in rabbits. Blood pH was on the acid side with propanol, butanol, & isobutanol, and on the alkaline side with isopropanol & sec-butanol, but no change was observed with ethanol & tert-butanol. Butanol & isobutanol had the lowest rate of urinary excretion. Acetaldehyde and acetic acid were detected as the urinary metabolites of ethanol and propanol, whereas isobutyraldehyde & isovaleric acid were the metabolites of isobutanol.
