ASTM E1064 - Water in Organic Liquids by Coulometric Karl Fischer Titration

We perform testing by ASTM E1064 to determine the water content in ethanol using a Karl Fischer reagent and automated coulometric titration procedure. Blends of denatured fuel ethanol and gasoline or similar hydrocarbons have a limited solvency for water. This solvency will vary depending on ethanol content, product temperature, and the base gasoline's aromatic content. A fuel blend of ethanol and gasoline contaminated by water will separate into a lower alcohol-rich aqueous phase and an upper hydrocarbon phase. Because normal spark-ignition engines will not run on the aqueous phase material, this separation is likely to cause serious operating problems. The phase separation of gasoline-ethanol blends is directly related to the total water content of the mixture.
