Date Aug. 21, 1997Quaternized imidazoles I in which R1 and R3 independently of one another are saturated or unsaturated hydrocarbon radicals of 1-12 carbon atoms which can be substituted by oxygen-functional groups or interrupted by nonadjacent oxygens, R2, R4 and R5 independently of one another are hydrogen or saturated or unsaturated hydrocarbon radicals of 1-12 carbon atoms which can be substituted by oxygen-functional groups or interrupted by nonadjacent oxygens, it being possible for R4 and R5, together with the corresponding imidazole carbons, to form a five- or six-membered ring, and X(-) is an anion, are used as corrosion inhibitors in the corrosion protection of nonferrous metals, especially for car radiator protection.

    Abstract: An antifreeze concentrate based on alkylene glycols or their derivatives is free from silicate, borate and nitrate contains (a) 0.05-10 wt.% 3-16 C carboxylic acid(s) in the form of alkali metal or (substituted) ammonium salt(s) and (b) 0.01-3 wt.% hydrocarbotriazole(s) and/or hydrocarbothiazole(s), especially benzotriazole and/or tolutriazole. Also claimed is a ready-to-use aqueous antifreeze composition containing water and 10-90 wt.% of the concentrate.
