    Abstract

    A simple and green method for the determination of the iodine number in biodiesel is proposed based on the Friedmann procedure for oils and fats adapted for biodiesel. The reagent solutions used are prepared in water with the exception of the standard iodine and the biodiesel solutions that are dissolved in ethanol 96 %. The method was compared with the procedure recommended by the norm EN 14111, which is essentially the Wijs method. Biodiesel derived from several oils and fats were analyzed using the two methods. A statistical comparison between them shows that both offer equivalent results and precision.
