The estimation of glycerol and some other hydroxylated compounds

Abstract

Abstract A method has been worked out for the estimation of glycerol by means of a complex copper compound. The failure of other methods on the same lines is ascribed to some properties of this compound and the mistakes made previously are avoided by working in alcoholic solution. Proofs are provided of the accuracy of the results obtained. In contrast with other methods, the estimation is very quick, does not involve a preliminary purification for most of the glycerol containing liquids met with, does not estimate impurities such as trimethyleneglycol and sugars, and yields true results. The possibilities of adapting the method to mannitol, sorbitol, tartaric acid, etc. are outlined.
