Abstract:
The ASTM D4806 denatured fuel ethanol specification limits the water content to a maximum of 1.0% vol. Therefore the final ethanol blended gasoline such as E10 can contain 0.1% water. E15 can contain 0.15% water. Water content is controlled because of the possibility of phase separation if the water level in the blend rises too much or if the temperature of the fuel drops. A bottom layer in a retail or car tank is obviously a problem. Water content is normally determined by Karl Fischer titration. This paper will offer an alternative GCVUV technique to quantify water in denatured fuel ethanol and ethanol-gasoline blends.
