The determination of the true iodine numbers of oils containing conjugated double‐bond systems

Leo Klee, Graham Harvey Benham

Open publisher page 26 citations

Abstract

Summary The modified Rosenmund‐Kuhnhenn procedure, as described by Benham and Klee, has been applied to conjugated systems. The only difference is that the 1‐minute reaction time is extended to 30–120 minutes depending upon sample weight and excess reagent. Such a procedure gives true iodine numbers and has been investigated for various tung oils, oiticica oil, isomerized fatty acids, and dehydrated castor oil.
