Abstract : Studies with Pb-Sn alloys were completed with the exception that additional exchange studies between nonadecanoic acid adsorbed on the alloy surface and in cyclohexane solution in contact with the surface should be performed. Lead-tin alloys showed adsorption and exchange characteristics which are much more like those of Pb than of Sn. Studies of the adsorption of nonadecanol on freshly machined metal surfaces indicate little adsorption of this alcohol. Studies of the adsorption, oleic and linoleic acids on freshly machined metals indicate that greater monolayer coverage can be obtained (assuming smooth surfaces) under conditions where a maximum of monolayer coverage is found when saturated acids were employed. Water monolayers produced under the surface pressure of spreading castor oil give essentially the anticipated compressed monolayer value for oleic acid, but only two-thirds of the expected value with linoleic acid.
