The Semi-Quantitative Identification of Hydrophobes in Normal Alcohol Ethoxylates by Hydriodic Acid Cleavage and Reversed-Phase HPLC Analysis with UV Detection

Abstract A method is described for the quantitative reversed-phase HPLC analysis of n-alkyl iodides obtained from HI cleavage of linear alcohol ethoxylated surfactants. The method is an improvement over previous techniques in that the detection is both iodide specific and is demonstrated for carbon chain lengths from 1 to 18.
