Rapid determination of double‐bond positions in monoenoic fatty acids by periodate‐permanganate oxidation

Donald T. Downing, Richard S. Greene

Abstract

Tetramethylammonium hydroxide has been used in the extraction and pyrolysis methylation of the carboxylic acids produced by periodate-permanganate oxidation of monounsaturated fatty acid methyl esters. This modification of the von Rudloff procedure allows rapid determination of double-bond positions and analysis of mixtures of positional isomers of monoenoic fatty acids.
