Abstract: The invention relates to antifreeze concentrates which are characterized in that they a) comprise at least one alcohol which can be mixed with water and which lowers the freezing point; b) at least one corrosion inhibitor; and c) at least one mononuclear or polynuclear aromatic component which carries at least one hydroxyl group, has a high buffering capacity in the pH range of approximately 6 to 10, and which is used as a reserve alkalinity dispenser. The invention also relates to coolant compositions containing these antifree ze concentrates for cooling circuits in internal combustion engines.

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.

Abstract: Imidazoles cuaternarios I, en donde R1 y R3, independientemente una de la otra, son radicales de hidrocarburos saturados o no saturados de 1-12 átomos de carbono que se pueden substituir por grupos funcionales de oxígeno o interrumpidos por oxígeno no adyacentes, R2, R4 y R5 independientemente uno del otro son radicales hidrogeno o hidrocarburos o saturados o no saturados de 1-12 átomos de carbono que se pueden substituir con grupos funcionales de oxígeno o interrumpidos mediante oxígenos no adyacentes; es posible que R4 y R5, junto con los carbones de imidazoles correspondientes formen un anillo de cinco o seis miembros, y X es un anion, se utilizan como anticorrosivos en la proteccion a la corrosion de los metales no ferrosos, especialmente para la proteccion del radiador del automovil.
