Apstrakt

Applicable to the analysis of glycerines free from organic compounds other than glycerol having more than two hydroxyl goups on adjacent carbon atoms, such as sugars which can also give rise to formic acid and, for this reason, will interfere in the determination. The procedure begins with a cold oxidation of the glycerol by sodium periodate in a strongly acid medium, followed by titration of the formic acid produced by the reaction with standard volumetric sodium hydroxide solution, using a pH meter.
