Abstract
The presence of salt water in marine oils is determined aboard ship by using a unique combination of reagents comprising a halogenated hydrocarbon, an inorganic salt solution and an alcohol to efficiently separate the water and then using a salt-impregnated gel to determine the chloride content.
Claims10
An improved method for determining the presence of salt water in a lubricating oil which comprises the steps of extracting the oil with an aqueous medium and contacting said aqueous medium containing chloride ion with a composite comprising silver chromate deposited on an adsorbent, the improvement whereby the aqueous medium used to extract the chloride ion is a combination of aqueous alkali metal or ammonium salt, an aliphatic monohydric alcohol and a halohydrocarbon or mixed halohydrocarbons.
