Abstract
Osmometric studies on the state of solution of mixtures of rust inhibitors have been made. Mixtures of rust inhibitors investigated here have been found to dissolve in oils forming various mixed micelles.
The degree of interaction of sodium dinonylnaphthalene sulfonate with other rust inhibitors is in the following order:
Potassium abietate>Duomeen-T dioleate>Pentaerythritmonoisostearate>Lead naphthenate
The degree of interaction of sodium dinonylnaphthalene sulfonate with lead naphthenate in hydrocarbon solvents increases with the decrease in the solubility parameters of the solvents due to the enhancement of the solute-solute interaction of the dual solutes.
The activity of mixtures of rust inhibitors in the commercial rust preventive oils decreases by the formation of mixed micelles.
