In this investigation, an apparatus was developed for the measurement of surface tension and of film pressures by means of an analytic balance, namely, a Christian Becker Chainomatic Balance. The applicability of this method to the measurement of spreading coefficients has been determined, and the spreading coefficients of a number of pure liquids have been determined. The spreading coefficients of a series of solutions of varying composition have been determined for two pairs of liquids. The spreading pressure of benzene and nitrobenzene are reported, as well as the spreading coefficients on stearic acid and palmitic acid of benzene, toluene, chloroform, isoamyl chloride, aniline, anisole, and diethyl carbonate.
