Definitions

  • This invention relates to new and improved corrosion preventive oils and greases. It particularly pertains to solution-stable mineral oil compositions containing dissolved amounts of certain organic polyhydric alcohols which provide an unusual degree of protection against corrosion to ferrous metals and also against corrosion of other metals and alloys such as copper, brass, bronze, I
  • oil-soluble organic sulfonic acids are known as mahogany acids as distinguished from green acids or watersoluble sulfonic acids and are most readily obtained as a by-product from the treatment of petroleum (for example, lubricating oil fractions) with sulfuric acid.
  • oil-soluble sulfonic acids may also be'obtained from the treatment of many other organic compositions such as alkyl benzenes, alkyl naphthalenes, coal tars, etc. with concentrated sulfuric acid, or by treatment of aliphatic or cycloaliphatic compounds such as C10 and higher hydrocarbons with chlor sulfonic acid, 55'
  • ester alcohols One reason for the harmful efiect of excessive amounts of the sulfonate probably lies in the mechanism of the corrosion inhibition by ester alcohols. This mechanism apparently involves plating out of the alcohol from its solution on thev metal surface. The closer the solution is to its saturation point with respect to the ester a1- cohol, the more easily is the latter plated out. For this reason, the esteralcohol must be only little soluble in the hydrocarbon medium, and in general best results are obtained with ester alcohols whose solubility at normal room temperature in hydrocarbon oils is below that of effective inhibiting concentrations, so.
