Abstract: Quaternized imidazoles I (see formula 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.THETA. 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.

Abstract: \\ The present invention relates to novel silicate-, borate- and nitrate-free antifreeze concentrates based on alkylene glycols or derivatives thereof which include an inhibitor combination essentially comprising salts of carboxylic acids together with hydrocarbon-triazoles and/or -thiazoles. These antifreeze concentrates are, in particular, entirely free from any salts of inorganic acids as corrosion inhibitors. The invention also relates to ready-to-use aqueous coolant compositions comprising these antifreeze concentrates.
