Abstract

A convenient, useful and efficient method and apparatus for determining the amount of alcohol contained in fuels. It is particularly useful for measuring the alcohol content of jet fuel, and is practiced by mixing a known amount of the fuel to be measured with a known amount of emulsion, the emulsion comprising a known amount of 8-Hydroxyquinoline ester of the O-vanadic acid. A resulting reaction causes a portion of the mixture to discolor, the amount of discoloration indicating the alcohol content of the fuel. This process can be performed in an apparatus comprising a tube with all of the necessary chemicals pre-mixed, thereby only requiring the addition of the fuel to be tested. Such an apparatus can be prepared in advance, sealed, and stored for a period of up to 2 years.
