Description

Verfahren zur Verminderung des korrodierenden Einflusses von Wasser und wäßrigeil Lösungen auf Eisen Aus dem Patent 748 650 und seinen Zusatzpatenten ist bekannt, zur Verminderung des korrodierenden Einflusses von Wasser oder wäßrigen Lösungen, deren p.H-Wert 6,5 nicht unterschreitet, auf Metalle oder metallische Gegenstände den Flüssigkeiten Salze von ein- oder mehrbasischen Äther- bzw. Thioäthercarbonsäuren zuzusetzen.Process for reducing the corrosive influence of water and aqueous solutions on iron It is known from patent 748 650 and its additional patents to reduce the corrosive influence of water or aqueous solutions, the pH of which does not fall below 6.5 , on metals or metallic objects to add salts of monobasic or polybasic ether or thioether carboxylic acids to the liquids.

In Weiterbildung dieser Verfahren wurde nun gefunden, daß man statt der Salze von Athercarbonsäuren, deren Herstellung mitunter mit Schwierigkeiten verbunden ist, auch die Salze solcher Carbonsäuren verwenden kann, deren Kohlenstoffolge durch eine Carbon- oder Sulfonamidgruppe unterbrochen ist. Als geeignet sind die Säuren der allgemeinen Formel R - X - R' - C 0 0 H befunden worden, in der R einen zwei- oder mehrkernigen perhydrierten, fünf- oder sechsgliedrigen Kohlenwasserstoffrest bedeutet, R' ein Alkylen- oder Arylenrest ist, der auch substituiert oder durch Heteroatome bzw. Heteroatomgruppen unterbrochen sein kann, und X für die Gruppe - C 0 - N R" - bzw. - S 0, - N R" - steht, in welcher R" Wasserstoff oder einen beliebigen Kohlenwasserstoffrest, der auch saure Gruppen enthalten kann, bedeutet. Man verwendet diese Säuren gewöhnlich in Form ihrer Alkalisalze, jedoch sind auch Salze organischer Basen geeignet, insbesondere dann, wenn es sich um die Verwendung in Gegenwart nicht wasserlöslicher Flüssigkeiten handelt. Die erfindungsgemäß vorgeschlagenen korrosionsverhindernden Mittel besitzen einen großen Anwendungsbereich, da sie nicht nur für Eisen oder Eisenlegierungen, für die sie in erster Linie in Betracht kommen, geeignet sind, sondern auch Aluminium, Magnesium und Kupfer sowie deren Legierungen zu schützen vermögen.In a further development of this process, it has now been found that, instead of the salts of ether carboxylic acids, the preparation of which is sometimes associated with difficulties, the salts of carboxylic acids whose carbon sequence is interrupted by a carboxylic or sulfonamide group can also be used. The acids of the general formula R - X - R ' - C 0 0 H have been found to be suitable, in which R is a two- or polynuclear perhydrogenated, five- or six-membered hydrocarbon radical, R' is an alkylene or arylene radical, which is also substituted or interrupted by heteroatoms or heteroatom groups, and X represents the group - C 0 - N R " - or - S 0, - N R" - , in which R "is hydrogen or any hydrocarbon radical which is also acidic These acids are usually used in the form of their alkali metal salts, but salts of organic bases are also suitable, especially when they are used in the presence of non-water-soluble liquids. The corrosion-inhibiting agents proposed according to the invention have a wide range of applications, since they are not only suitable for iron or iron alloys, for which they are primarily suitable, but also aluminum, magnesium and K able to protect copper as well as their alloys.

Die Herstellung der als korrosionsverhindernde Mittel vorgeschlagenen Carbonsäuren erfolgt nach allgemein bekannten und üblichen Methoden, indem man beispielsweise die Carbon- oder Sulfonsäurehalogenide von zwei- oder mehrkernigen cycloaliphatischen Kohlenwasserstoffen, wie Dekahydronaphthalin, Dicyclohexyl, Dicyclopentyl, Dicyclohexyl-i, 2-äthan, Dicyclohexyl-i, 6-hexan, Tetradekahydrophenanthren oder deren Substitutionsprodukte mit Amino- oder Iminocarbonsäuren, zweckmäßigerweise in Gegenwart säurebindender Mittel zur Umsetzung bringt. An Amino- bzw. Iminosäuren kommen für die Umsetzung beispielsweise in Betracht Aminoessigsäure, ß-Aminopropionsäure, ß-Amino-buttersäure, ö-Amino-valeri-ansäure, m-Arnino-benzoesäure, p-Amino-ziintsäure, Imino-diessigsäure u. a. Man kann selbstverständlich die Herstellung der beanspruchten Carbonsäuren auch in der Weise bewerkstelligen, daß man die Carbon- bzw. Sulfonsäureamide der cycloaliphatischen Kohlenwasserstoffe mit Carbonsäuren, die ein leicht austauschbares Halogenatom besitzen, umsetzt.The manufacture of those proposed as corrosion preventive agents Carboxylic acids are carried out by generally known and customary methods, for example by the carboxylic or sulfonic acid halides of di- or polynuclear cycloaliphatic Hydrocarbons such as decahydronaphthalene, dicyclohexyl, dicyclopentyl, dicyclohexyl-i, 2-ethane, dicyclohexyl-i, 6-hexane, tetradecahydrophenanthrene or their substitution products with amino or iminocarboxylic acids, expediently in the presence of acid-binding agents Bringing funds to implementation. Amino or imino acids are used for the implementation For example, aminoacetic acid, ß-aminopropionic acid, ß-amino-butyric acid, ö-Amino-valeric acid, m-Amino-benzoic acid, p-Amino-ziintic acid, imino-diacetic acid i.a. You can of course produce the claimed carboxylic acids also accomplish in such a way that the carboxylic or sulfonic acid amides of cycloaliphatic hydrocarbons with carboxylic acids that are easily exchangeable Have halogen atom, converts.

Beispiele i. Ein Zusatz von o,5 0/, des Natriumsalzes der N-Methyldekahydronaphthalinsulfamidoessigsäure zu Gebrauchswasser verhindert die korrodierende Wirkung desselben auf eiserne Gegenstände, so daß es als Sperrflüssigkeit für Meßgeräte verwendbar ist.Examples i. An addition of 0.50 /, of the sodium salt of N-methyldekahydronaphthalenesulfamidoacetic acid to service water prevents the corrosive effect of the same on iron objects, so that it can be used as a barrier fluid for measuring instruments.

2. Versetzt man ehr Schleifwasser mit 1 0/, des Natriumsalzes der Dicyclohexylsulfamido-fl-propionsäure, so findet keine Rostbildung auf den beim Schleifvorgang benutzten metallischen Gegenständen statt.2. Puts one ore grinding water with 1 0 /, the sodium salt of Dicyclohexylsulfamido-fl-propionic acid, no rust formation takes place on the used during grinding metal objects.

3. Löst man in 77 Gewichtsteilen Spindelöl 13 Gewichtsteile des Ammoniumsalzes der Dekahydronaptithalinsulfimidodiessigsäure unter Zusatz von io Gewichtsteilen Dodecylalkoholpolyglykoläther auf, so erhält man eine Mischung, die beim Einrühren in Wasser (2 g/l) eine vor Rost schützende Emulsion liefert, die sich als Schmier- und Bohröl eignet. 3. If 13 parts by weight of the ammonium salt of decahydronaptithalinsulfimidodiacetic acid are dissolved in 77 parts by weight of spindle oil with the addition of 10 parts by weight of dodecyl alcohol polyglycol ether, a mixture is obtained which, when stirred into water (2 g / l), gives an emulsion that protects against rust and acts as a lubricant - and drilling oil is suitable.

4. Durch Vermischen des Cyclohexylaminosalzes der Perhydrophenanthrensulfamidoessigsäure mit der 2o- bis 25fachen Menge Motorenöl erhält man ein gut wirksames Korrosionsschutzöl.4. By mixing the cyclohexylamino salt of perhydrophenanthrene sulfamidoacetic acid a very effective anti-corrosion oil is obtained with 2 to 25 times the amount of motor oil.
