Abstract: PROBLEM TO BE SOLVED: To obtain nonfreezing concentrate to which all kinds of metals used in engines, particularly aluminum, are corrosion-resistant, and is useful in motor cars and the like by admixing prescribed amounts of a specific carboxylate salt and a hydrocarbon triazole and the like to an alkylene glycol (derivative). SOLUTION: This is a nonfreezing concentrate free from silicate, borate and nitrate and comprises an alkylene glycol, for example, ethylene glycol, or its derivative, as a base material, (A) 0.05-10wt.% (based on the whole amount of' the concentrate) of' one or more alkali metal or (substituted) ammonium salts of' a 3-l6C carboxylic acid such as pentanoic acid or suberic acid and (B) 0.01-(3wt.% of one or more hydrocarbon triazole and/or hydrocarbon thiazole, particularly benzotriazole and/or tolutriazole, in addition, preferably (C) 1wt.% of a hard water stabilizer, for example, polyacrylic acid. This nonfreezing concentrate is admixed to water in an amount of 10-90wt.% to give a water-based coolant composition.

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 invention concerns the use as corrosion-inhibitors of quaternized imidazoles (I), wherein R and R , independently of each other, designate saturated or unsaturated C1-C12 hydrocarbon groups which can be substituted by groups having an oxygen function or interrupted by non-adjacent oxygen atoms; R , R and R , independently of one another, designate hydrogen or saturated or unsaturated C1-C12 hydrocarbon groups which can be substituted by groups having an oxygen function or interrupted by non-adjacent oxygen atoms, R and R being able to form a five- or six-member ring together with the corresponding imidazole carbon atoms; and X stands for an anion. These substances are used for protecting nonferrous metals against corrosion, in particular for protecting radiators in the automotive field.
