1 Claim-f (oi.- iii-es) 7 held by the metal surface, probably by adsorp- The present invention relates to-a method for inhibiting or preventing the rusting of ferrous metal surfaces, and particuiarb iron or steefsurfaces which may be subjected to conditions nor- 5 mally conducive to rusting. The present invention is particularly applicable to the prevention of. rusting of 'iron or steel sheets or plates, bars. tubes, wire, and articles fabricated from iron orsteel by 1 rolling, grinding or machining.
A principal object of this invention is the inhibition or prevention of rusting of ferrous metal surfaces by the application thereto of a him of oil invention are preferably hydrocarbon oils having 4 a Saybolt Universal viscosity'at 100 F. of at least 60 seconds, and substantially free of constituents tendingto stain, corrode orv react with ferrous metal surfaces. Hydrocarbon oils derived from paraflin base or naphthene base petroleum, or oils 7 produced by solvent extraction, hydrogenation. or.
other means may be suitably employed. In general the oil component 'of the rust-preventing composition comprises about 90% or more of the '30 composition.
The synthetic esters to be employed in conjunction with the hydrocarbon oil are preferably those derived by the reaction of aliphatic or aromatic alcohols or phenols with carboxylic acids, preferably saturated carboxylic acids having from about 8 to about 25. carbon atoms per molecule.
, Among the alcohols may be mentioned methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, the butyl alcohols, the amyl and hexyl 4 1! alcohols, cetyl alcohol, the glycols, glycerol, phenol, cresol, naphthol, benzyl alcohol and the like. The organic acids may be exemplified by caprylic acid, capric acid, undecylic acid, lam'lc acid, myr'lsticacidpalmiticacidmargaricacldstearie acid,.arachidic acid, cerotic acid, meli'ssie acid.
.the naphthenic acids. benaoic' acid, phthalic acid and the like. Quantities of the esters ofthe order of 1%,2%,5%.and 10% ormoremaybeadded to thehydrocarbonoilandtheadmixtureorsolution applied to rustable metal surfaces by dipping.

tion, and which is resistant to the penetration of moisture. Such films are non-drying and readily removable by wiping. washing with organic solvents, soap solutions or other detergents. The
oil-synthetic ester compositions utilized in accordance with this invention do not have the dis-' advantages inherent in the use of natural oils. fats, fatty oils and mixtures thereof with hydro carbon oil, which have been employed heretofore as rust-proofing agents. Many of the natural fatty oils are glycerides of unsaturated fatty acids, and when applied to metal surfaces in the undiluted state or admixed with hydrocarbon oil. form sticky or tacky films due to the oxidation and/or polymerlzationof the unsaturated con stituents. 'I'hese tacky films are dimcult to remove, since the oxidized constituents are relatively-insoluble in organic solvents and not readily removed 'by water or detergent solutions. Furthermore, many of the fatty oils contain varying amounts of free fatty acids which tend to corrode or stain the metal with which they come in contact. The fatty oils also tend to become rancid, particularly when exposed in relatively thin films to the action of air. However, the synthetic esters employed in conjunction with bydrocarbon oil in accordance with this invention do not form sticky or gummy deposits upon the ,metal surfaces, do not oxidize nor polymerize, nor become acidic nor rancid, and are readily removed from metal surfaces.
The following examples will serveto further illustrate my invention Test pieces of polished, cold rolled steel were coated with the rust-inhibiting compositions and exposed to the atmosphere (temperature 77' E; humidity 100%) for a period of one week. The viscodty of the min eral oil component is given in seconds Saybolt rusting. V bodmsting.

For brevity, herein and in the appended claim, the term viscous hydrocarbon oil" is to be understood to comprehend oils having a Baybolt Universal viscosity at 100 F. of 60 seconds or What I claim is: A method of inhibiting rusting of a ferrous naphthenates.
