Definitions
- a special method is drying with use of organic solvents.
- the water may be removed azeotropically by means of solvent vapors.
- certain surfaceactive compounds such as, for example, quaternary ammonium compounds, fatty acid polyglycol esters or similar compounds are added to these solvents.
- the displaced water easily becomes emulsified and then residues remain on the surface.
- An object of the present invention is the development of a composition and a process for removing adhering aqueous films or layers from metal surfaces while avoiding the drawbacks of the prior art.
- Another object of the invention is the obtaining of a composition for the displacing of an aqueous film or layer adhering to a metal surface consisting essentially of an organic waterimmiscible solvent selected from the group consisting of an organic water-immiscible solvent having a density of less than 0.9 gm./ml.
- said mixture having a density of less than 0.9 gm./ml., containing from 0.1 to 10 percent of an acid selected from the group consisting of monocarboxylic acid having from seven to 12 carbon atoms and mixtures of monocarboxylic acids having an average of from seven to 12 carbon atoms and from 0.1 to 8 percent of an alkylamine selected from the group consisting of alkylamines having from six to 10 carbon atoms and mixtures of alkylamines having an average of from 6 to 10 carbon atoms, the average sum of the carbon atoms in said acid and said alkylamine being from l to I7.
- an acid selected from the group consisting of monocarboxylic acid having from seven to 12 carbon atoms and mixtures of monocarboxylic acids having an average of from seven to 12 carbon atoms and from 0.1 to 8 percent of an alkylamine selected from the group consisting of alkylamines having from six to 10 carbon atoms and mixtures of alkylamines having an average of from 6
- a yet further object of the invention is, in the process of removing an adhering aqueous film or layer from a metal surface by the steps of displacing said adhering aqueous film or layer on a metal surface with an organic solvent composition and removing said organic solvent from said metal surface the improvement which comprises utilizing, as said organic solvent composition, a composition for the displacing of an aqueous film or layer adhering to a metal surface consisting essentially of an organic water-immiscible solvent having a density of less than 0.9 gm./ml.
- said mixture having a density of less than 0.9 gm./ml., containing from 0.1 to percent of an acid selected from the group consisting of monocarboxylic acid having from seven to 12 carbon atoms and mixtures of monocarboxylic acids having an average of from seven to 12 carbon atoms and from 0.1 to 8 percent of an alkylamine selected from the group consisting of alkylamines having from six to 10 carbon atoms and mixtures of alkylamines having an average of from six to 10 carbon atoms, the average sum of the carbon atoms in said acid and said alkylamine being from 15 to 17.
- an acid selected from the group consisting of monocarboxylic acid having from seven to 12 carbon atoms and mixtures of monocarboxylic acids having an average of from seven to 12 carbon atoms and from 0.1 to 8 percent of an alkylamine selected from the group consisting of alkylamines having from six to 10 carbon atoms and mixtures of alkylamines having an average of from six to 10 carbon
- the present invention provides a composition, for the removal of aqueous liquid films or layers from a metal surface comprising a water-immiscible organic solvent, or mixture of such solvents having a density or an average density of less than 0.9 gm./ml., containing from 0.1 to 10 percent by weight of a monocarboxylic acid or a mixture of monocarboxylic acids, having an average of from seven to 12 carbon atoms and 0.1 to 8 percent by weight of an alkylamine having six to 10 carbon atoms, or a mixture thereof having an average of from six to 10 carbons atoms, the sum of carbon atoms in the carboxylic acid and the alkylamine being 15 to 17.
- the present invention provides a process for the removal of an aqueous liquid film or layer adhering to a metal surface comprising treating said metal surface with a water-immiscible organic solvent or a mixture of such solvents having a density or an average density of less than 0.9 gm./ml., containing from 0.1 to 10 by weight of a monocarboxylic acid, or a monocarboxylic acid mixture having an average of from seven to 12 carbon atoms, and 0.1 to 8 percent of an alkylamine with six to 10 carbon atoms, or a mixture thereof having an average of from six to 10 carbon atoms, the sum of carbon atoms in the carboxylic acid and alkylamine being l5 to 17, in order to displace said aqueous liquid film or layer from the surface of said metal surface.
- a water-immiscible organic solvent or a mixture of such solvents having a density or an average density of less than 0.9 gm./ml., containing from 0.1 to 10 by
- Hydrocarbon fractions with a density of less than 0.9 gm./ml. are generally suitable as the organic solvent mixtures immiscible with water. If desired, small amounts of chlorinated hydrocarbons may be added as long as they are water-immiscible and miscible with the hydrocarbon fractions and the average density of the mixture is less than 0.9 gm./ml.
- the carboxylic acids used may be straight or branched chains, natural or synthetic monocarboxylic acids or their mixtures, having an average of from seven to 12 carbon atoms in the molecule.
- alkanoic acids having from seven to 12 carbon atoms such as oenanthic acid, caprylic acid, pelargonic acid, capric acid, lauric acid or the branched acids corresponding to these carboxylic acids may be used.
- aromatic carbox ylic acids such as phenylalkanoic acids and alkylphenylalkanoic acids having from seven to 12 carbon atoms, especially benzoic acids, may also be used.
- the carboxylic acid used can preferably be a readily accessible, commercial fatty acid mixture which contains a preponderance of caprylic, capric and lauric acids.
- Such mixtures are obtained, for example, as the first distillate during the working up of natural fats and usually consist of about 50 percent of caprylic acid, 40 percent of capric acid and 5 percent of lauric acid, as well as small amounts of lower carboxylic acids.
- This mixture of alkanoic acids from the first distillate has an average of nine carbon atoms.
- Suitable alkylamines having six to 10 carbon atoms are preferably primary amines such as hexylamine, octylamine and decylamine, or mixtures thereof.
- the monocarboxylic acids or mixtures of monocarboxylic acids and the alkylamines or their mixtures are preferably used in approximatly equimolecular amounts. Small excesses of carboxylic acid or alkylamine, however, have no effect on the activity.
- compositions are preferably used which contain from 0.3 to 3 percent by weight each of carboxylic acid and alkylamine. Basically compositions with a content of carboxylic acid and alkylamine each of less than 0.3 percent can be also make, but their stability is too low for a technical product. With higher concentrations of carboxylic acid and aklylamine, alkylamine, a slight film remains on the metal surfaces which, however, exerts a positive influence on their storability.
- the total number of carbon atoms in the carboxylic acid and alkylamine should be to 17.
- the calculated average number of carbon atoms is decisive as the carbon number of the carboxylic acid and the alkylamine. If the carbon number is too small, multilayer liquid systems are formed on the introduction of water. The efficiency of the water displacement is too low. If, on the other hand, the total carbon atoms number is too high, emulsions are formed with the displaced water.
- the wet metal surfaces are preferably introduced for a short time into a bath which contains the above-indicated components.
- a treatment period of a few seconds is sufficient to free the metal surfaces from the adherent film of water.
- the displaced water is easily separated. No formation of emulsions occurs, so that the water can be easily removed.
- the metal parts are then taken out of the bath. After evaporating the solvent, hydrophobic surfaces from the residual acid and amine remain which give a temporary protection against corrosion.
- a customary fat for protection against corrosion such as for example wool fat or vaselines, can be incorporated in the compositions according to the invention.
- the total carbon number of the composition was therefore 14.
- a displacement of the film of water likewise occurred, but the water removed formed an emulsion at the interface with the organic phase, particularly when movement of the bath occurred when the parts were put in and taken out.
- EXAMPLE 3 Slightly soiled metal parts were treated with a neutral cleaner and then rinsed with water. The metal parts were then immersed in a bath of the following composition:
- a composition for the displacing of an aqueous film or layer adhering to a metal surface consisting essentially of an organic water-immiscible solvent selected from the group consisting of an organic water-immiscible solvent having a density of less than 0.9 gm./ml.
- a mixture of miscible organic water-immiscible solvents said mixture having a density of less than 0.9 gm./ml., containing from 0.1 to 10 percent of a monocarboxylic acid having an average of from seven to 12 carbon atoms selected from the group consisting of 1 alkanoic acids, 2) phenylalkanoic acids, 3) alkylphenylalkanoic acids 4) mixtures thereof and from 0.1 to 8 percent of an alkylamine selected from the group consisting of alkylamines having from six to 10 carbon atoms and mixtures of alkylamines having an average of from six to 10 carbon atoms, the average sum of the carbon atoms in said acid and said alkylamine being from 15 to 17.
- composition of claim 1 wherein said acid and said alkylamine are present in substantially equimolecular amounts.
- composition of claim 1 wherein said acid is a technical fatty acid mixture consisting preponderantly of caprylic, capric and lauric acids.
- composition of claim 1 wherein said acid is benzoic acid.
