Abstract


A simple and precise method for alkylresorcinols determination was elaborated. The method a based on coupling of alkylresorcinals with diazotized Fast Blue B, in acidified propaaiol. The method is highly specific for 5-n-alkyl derivatives of resorcinols. In case of rye and wheat 98.1% and 96.2% respectively of total extinction value were due to 5-n-alkylresorcinols.
