The reduction in gas desorption through surface active monolayers on a water substrate has been investigated for five compounds (1‐hexadecanol, 1‐octadecanol, 1‐docosanol, 1‐eicosanoic acid, and 1‐docosanoic acid) and four gases (oxygen, nitrogen, methane and carbon dioxide) at 25°C. Gas transport was retarded significantly at high surface coverage and decreased nonlinearly with change in surface coverage past the point equivalent to zero surface pressure. Interphase mass transfer coefficients for transport through the films were calculated, but no simple correlation could be discovered which could be used to predict film coefficients or the reduction as a function of surface coverage.
