Experimental study of film formation on metals in hydrocarbons

The purpose of this study was to provide certain quantitative information on the, corrosion of metals in insulating oils, and simultaneously to throw more light on the anions present in hydrocarbons. The process under study was the deposition of metal salts on a metal surface in contact with oil containing an aliphatic acid in solution. The metals that gave positive effects were copper, lead, and zinc. The aliphatic acid was carbon 14 labeled, and the small amounts deposited were determined by measurement of radioactivity of the metal, samples. The deposition was effected in one group of experiments by chemical action and in another group by electrochemical action.
