Abstract
A rapid titration method is described for the quantitative determination of both cyclopropenoid and epoxy fatty acid derivatives in mixtures. It was found that epoxy compounds can be titrated selectively with Durbetaki reagent at 3C without interference from cyclopropenoid derivatives. Cyclopropenoid derivatives can be titrated much more rapidly to a much sharper end point a 55C that at room temperature. Thus mixtures can be analyzed by first titrating at 3C to determine the epoxy compounds and then continuing the titration at 55C to determine the cyclopropenoid components.
