Analytical Method for Ethylene Dibromide Depletion in Aviation Gasoline

Abstract

The measurement of ethylene dibromide depletion in aviation gasoline is one criterion for evaluating the storage stability of coatings used for the corrosion prevention of tanks and containers used for the storage and protection of military petroleum based hydrocarbons fuels. The standard procedure for the determination of ethylene dibromide depletion is time-consuming, requires special equipment, and necessitates extraordinary care in handling. The method described affords an accurate, uninvolved procedure for measuring ethylene dibromide depletion; the procedure is free from hazardous operating conditions and is highly reproducible. It is based on the following reactions: BrCH2CH2Br over KOH yields CH2=CHBr and BrCH2CH2Br + KOH yields CH2=CHBr + KBr + H2O, then AgNO3 + KBr yields AgBr precipitate.
