Conclusions

  1. 1.

    A gas-adsorption method was used to determine the latent heat of sublimation of hexamethyleneimine benzoate (∼27 kcal/mole) and the number of hexamethyleneimine m-nitrobenzoate molecules adsorbed per square centimeter of iron and nickel powders (2·1011 and 6·1011, respectively).

     
  2. 2.

    The method makes it possible to study the adsorption of inhibitors at extremely low degrees of surface coverage and also to determine the vapor pressures and heats of sublimation of volatile corrosion inhibitors.
