A simple method for estimation of cetane index of vegetable oil methyl esters

  • Kanit Krisnangkura


This article illustrates a simple method for estimation of cetane indexes of vegetable oil methyl esters from their saponification and iodine numbers. The range of the calculated values covers all the cetane numbers of vegetable oil methyl esters determined experimentally. when it was applied to individual fatty acid methyl esters from C8 to C24, a straight line parallel to that of Klopfenstein was obtained.
