Description

Es ist bekannt, dass langkettige Alkyl- und Alkylarylsulfonate sowie langkettige Alkylsulfonamidocarbonsäuren in Form ihrer Salze als wasserlösliche bzw. in Wasser emulgierbare Kühl- und Metallbearbeitungsmittel verwendet werden.It is known that long-chain alkyl and alkylarylsulfonates and long-chain alkylsulfonamidocarboxylic acids in the form of their salts are used as water-soluble or water-emulsifiable cooling and metalworking agents.

Auch ölfreie, wasserlösliche, korrosionsinhibierende Metallbearbeitungsmittel in Form von Salzen der Sulfonamidocarbonsäuren wie sie beispielsweise im deutschen Bundespatent 1 298 672 und in der deutschen Offenlegungsschrift 2 330 978 beschrieben werden, wurden schon vorgeschlagen.Oil-free, water-soluble, corrosion-inhibiting metalworking agents in the form of salts of sulfonamidocarboxylic acids, as described, for example, in German Federal Patent 1,298,672 and in German Offenlegungsschrift 2,330,978, have also been proposed.

Diese Mittel haben den Nachteil, dass sie biologisch nicht oder nur schwer abbaubar sind, und deshalb für das Ablassen in Kläranlagen nach ihrer Benutzung problematisch sind.These agents have the disadvantage that they are not biodegradable or only with difficulty, and are therefore problematic for draining into sewage treatment plants after their use.

Es ist deshalb von besonderer Bedeutung für den Umweltschutz, ölfreie, wasserlösliche und biologisch leicht abbaubare korrosionsinhibierende Kühl- und Metallbearbeitungsmittel einzusetzen.It is therefore of particular importance for environmental protection to use oil-free, water-soluble and easily biodegradable corrosion-inhibiting coolants and metalworking agents.

Es wurde nun überraschend gefunden, dass Alkali- und Aminsalze von Amidocarbonsäuren der allgemeinen FormelIt has now surprisingly been found that alkali and amine salts of amidocarboxylic acids of the general formula

einen sehr guten Korrosionsschutz, eine hervorragende Schmierwirkung und trotz ausgezeichneter Grenzflächenaktivität eine geringe Schaumwirkung besitzen, sowie biologisch leicht abbaubar sind. In der Formel bedeuten R[hoch]1 einen Fettsäure-(Alkyl-CO-)rest mit etwa 6 bis 20 Kohlenstoffatomen, R[hoch]2 den Rest R[hoch]1 oder das Radikal -(CH-(R[hoch]4)-(CH[tief]2)[tief]n-COOH oder ein Wasserstoffatom, R[hoch]3 das Radikal -(CH-(R[hoch]4)-(CH[tief]2)[tief]n-COOH oder oder , have very good corrosion protection, an excellent lubricating effect and, despite excellent interfacial activity, have a low foaming effect and are easily biodegradable. In the formula, R [high] 1 denotes a fatty acid (alkyl-CO-) radical with about 6 to 20 carbon atoms, R [high] 2 denotes the radical R [high] 1 or the radical - (CH- (R [high]) 4) - (CH [low] 2) [low] n-COOH or a hydrogen atom, R [high] 3 the radical - (CH- (R [high] 4) - (CH [low] 2) [low] n -COOH or or ,

R[hoch]4 einen Alkylrest mit 1 bis 3 Kohlenstoffatomen oder ein Wasserstoffatom, m eine ganze Zahl von 2 bis 6, n von 0 bis 2 und z eine solche von 1 bis 6.R [high] 4 is an alkyl radical having 1 to 3 carbon atoms or a hydrogen atom, m is an integer from 2 to 6, n is from 0 to 2 and z is from 1 to 6.
