Method for testing gasoline for water and alcohol in the presence or absence of the other
Abstract
A method is described for detecting the presence of water from a chemical color reaction comprising the steps of: (A) preparing a suspension of approximately 2% anhydrous sodium borate plus 0.1% methylene blue dye in mineral oil; (B) contacting said suspension with a sample of fuel to be tested; (C) reacting any water in said sample of fuel with said suspension to produce a color change; observing said color change if water is present in said fuel, wherein said fuels comprise liquid hydrocarbon fuel. A method is described for detecting the presence of alcohols in fuels from a chemical color reaction comprising the steps of: (A) preparing a suspension of approximately 0.1 % gentian violet dye in mineral oil; (B) contacting said suspension with fuel to be tested; (C) reacting any alcohol in said sample of fuel with said suspension to produce a color change; observing said color change if alcohol is present in said fuel, wherein said fuels comprise liquid hydrocarbon fuel. A method is described for measuring the amount of alcohol in fuels from a chemical extraction comprising the steps of: (A) preparing an aqueous solution consisting of 9% nitric acid; (B) preparing a test vial with amore »
