I have to elucidate the formation of various propyl esters in my biodiesel samples and quantify them for optimization purposes. I'm guessing that when propanol is used as the reacting alcohol, the esters formed are propyl esters and cannot be compared to the FAME standard such as 'Supelco 37 FAME mix'. I cannot find a reference standard mix for comparative analysis.
Mr Bisheswar, generally fatty acid Propyl esters may not available as reference standards. Either you have to use methanol as a reacting alcohol or you have to prepare propyl esters of standard fatty acids with your self, which you can use as a standard.
You can check our paper in Energy journal or Renewable Energy journal.
We describe in the GC part.
My paper is available in my individual page.
Thanks
