Definitions

  • oils and oil-containing emulsions come into contact with metal surfaces at high temperatures, the liquid media containing more or less large amounts of water. These result in part from the particular process taking place, as is the case, for example, with steam turbines, but can also be a desired component of the respective liquid media. In all such cases, protecting the metal surfaces coming into contact with the liquid media against corrosion poses a significant problem. Iron or iron-containing alloys in particular are corroded by water or moisture in the process liquids. The result in the ongoing process is a reduction in the service life of the respective system or, in the case of further processing of the metal surfaces, the need for complex cleaning of the metal surfaces in preparation for subsequent process steps, for example by phosphating, electroplating, painting, etc.
  • a corrosion inhibitor is added to the process, cleaning or cooling liquids in such cases, which should inhibit, if not completely suppress, the corrosion.
  • DE-AS 11 49 843 and EP-PS 0 002 780 describe amine salts of amic acids which are obtained by reacting succinic or maleic anhydride with primary alkylamines, and alkanolamine salts of maleic acids as corrosion inhibitors for fuel and lubricating oils and also water containing systems called.
  • such compounds have the disadvantage that they tend to foam very strongly or - with a low tendency to foam - lose a large part of their corrosion-inhibiting effect.
  • DE-AS 12 98 672 also discloses alkali or amine salts of sulfonaminocarboxylic acids, which likewise have a good corrosion protection effect in known metalworking fluids or oil-containing oil emulsions.
  • a disadvantage of these compounds is that they are to be regarded as relatively toxic and their use is therefore subject to severe restrictions.
  • alkanolamine salts of certain alkenylsuccinic acids are also known which, in aqueous systems without foam formation, show good corrosion protection on metal surfaces made of iron or iron-containing alloys.
  • EP-A 0 127 132 also discloses alkenylsuccinic acid halamides as corrosion inhibitors, which are also described in aqueous process fluids for drilling, cutting or rolling metals. In aqueous media in particular, however, hydrolysis of the succinic acid derivatives mentioned is observed, which drastically reduces the corrosion-inhibiting effect of such compounds.
  • the invention relates to the use of alkoxyhydroxy fatty acids and their salts of the general formula (I) in the R for unbranched alkyl radicals or alkenyl radicals with 6 to 8 C atoms, R 2 for unbranched or branched alkyl radicals with 1 to 18 C atoms or for unbranched or branched alkenyl radicals with 2 to 18 C atoms, M for hydrogen or organic ammonium radicals with one or more alkyl radicals or hydroxyalkyl radicals on the nitrogen atom and m are integers in the range from 3 to 13, in quantities of 0.01 to 10% by weight, based on oil, as corrosion inhibitors in oils and oil-containing emulsions.
  • the compounds of the general formula (I) which are used according to the invention for corrosion inhibition are known as such.
  • the process for their preparation is described in the relevant literature, for example in DE-OS 33 18 596.
  • Alkoxyhydroxy fatty acids and their salts of the general formula (I) are formed, for example, by the fact that fatty acids or their esters of the general formula (II) in which R1 and m have the meanings given above and M can represent hydrogen or an alkyl group, preferably alcohols occurring in natural fats or oils, are epoxidized by methods known per se. Such an epoxidation reaction can take place, for example, by reacting the fatty acids or their esters of the general formula (II) with organic peroxo acids under suitable conditions.
  • the epoxides obtained in this way which carry the oxirane ring at the position in the molecule at which the olefinic double bond was found in the starting materials, are then, according to processes which are also known per se, by acid-catalyzed ring opening with alcohols of the general formula in which R 2 can have the meanings given above, converted into the corresponding alkoxyhydroxyfatty acid derivatives in which the alkoxy group R 2 0 and the H y -droxy group each on the two carbon atoms connected in the starting material by the olefinic double bond are connected.
  • the terminal ester grouping of the epoxides can also be transesterified.
  • esters resulting from this reaction sequence are then subjected to alkaline hydrolysis by methods which are also known per se, giving the salts of the general formula (I) in which M represents organic ammonium radicals having one or more alkyl or hydroxyalkyl radicals on the nitrogen atom. If appropriate, the corresponding salts can be converted into the corresponding acids (I) in which M represents hydrogen by adjusting an acidic pH in the reaction medium.
  • fats and oils of the general formula (II) are preferably used, which are inexpensively available in large quantities from native sources.
  • Soybean oil which has a high content of oleic acid and linoleic acid, sunflower oil, sesame oil, corn oil, cottonseed oil, palm oil or coconut oil are preferred.
  • Such natural fats and oils contain high proportions of esters of unsaturated fatty acids of the general formula (I), in which R represents unbranched alkyl radicals or alkenyl radicals, for example with 8 carbon atoms.
  • esters of different chain lengths can also be found in such oils of native origin; for example, in soybean oil one can find mixtures of fatty acid esters of the general formula (II) in which R represents alkyl and alkenyl radicals with 8 carbon atoms, the saturated and unsaturated ones Shares to each other in the weight ratio of Stand 1: 2.
  • Such compounds are to be regarded as preferably usable in the sense of the present invention.
  • the alcohols of the general formula (III) used for the alcoholysis of the oxirane ring contain unbranched or branched alkyl radicals with 1 to 18 carbon atoms or unbranched or branched alkenyl radicals with 2 to 18 carbon atoms.
  • Unbranched alkyl radicals or alkenyl radicals with 8 to 18 carbon atoms are to be regarded as preferred, which can also be provided inexpensively in large quantities from native sources.
  • alcohol mixtures of natural origin are used which have unbranched alkyl radicals with 16 carbon atoms and alkenyl radicals with 18 carbon atoms.
  • the free alkoxyhydroxy fatty acids (I) in which M represents hydrogen can be used as corrosion inhibitors.
  • Preferred cations of such salts are ammonium cations which carry two or three alkyl radicals or hydroxyalkyl radicals on the nitrogen atom.
  • the salt (I) in which M stands for a diethanolammonium radical is particularly preferably used.
  • the alkoxyhydroxy fatty acids mentioned and their salts of the general formula (I) given are in Lubricating oils, greases, power transmission oils and metalworking emulsions based on mineral oils are used as corrosion inhibitors. They are used in a wide range of quantities in oils or oil-containing emulsions. The amounts can vary in the range from 0.01 to 10% by weight, based on the oil base, and are preferably from 0.05 to 0.5%. Oils and oil-containing emulsions which contain alkoxyhydroxyfatty acids or their salts of the general formula (I) in these amounts show a corrosion protection on iron and iron-containing metal surfaces which is at least equivalent to the previously known compounds.
  • the alkoxyhydroxy fatty acids mentioned or their salts are superior to the previously known compounds in that they can be made inexpensively accessible in large quantities from natural raw materials.
  • test specimens were stored in solutions without inhibitor (cf. 1) or in the corresponding mixtures, which contained a commercially available alkenylsuccinic acid half-ester, the concentration of which corresponded to the concentration of the alkoxyhydroxy fatty acids used according to the invention (cf. 2).
  • concentration of which corresponded to the concentration of the alkoxyhydroxy fatty acids used according to the invention cf. 2.
  • the emulsions were prepared from the corresponding concentrates by customary methods using water with a total hardness of 3.58 mmol CaCl 2 . 6H 2 0 and MgSO 4 . 7H 2 O manufactured.
  • the emulsions were prepared by stirring 8 to 25% by weight of the stated concentrates (formulations 1 and 2) in water with the stated total hardness. This corresponds to DIN 51360 / Part 2.
  • the corrosion protection S was then calculated in% according to the following equation from the comparison of the results with the averaged removals in the case of a blank sample made from inhibitor-free emulsion:
  • steel sheets (quality ST 1405, degreased and sanded, dimensions: 25 x 50 mm) were immersed in mineral oil emulsions which had been produced using the substances used according to the invention. Different amounts of inhibitor were used in the mineral oil emulsions. After a certain draining and drying time, the sheets were stored in a humidity chamber at 100% relative atmospheric humidity. After the test period (1 to 7 days), the steel sheets were checked for signs of corrosion. The evaluation was carried out on the evaluation scale given in Example 1 from 0 to 4.
  • Example 4 identical steel sheets of the same size were stored in mineral oil emulsions which did not contain an inhibitor.
  • the comparison emulsions contained naphthenic mineral oil and emulsifier (adduct of 6.5 EO with nonylphenol) in a weight ratio of 4: 1.
