Abstract: An antifreeze concentrate for cooling systems in fuel-cell drives which gives ready-to-use aqueous coolant compositions having a conductivity of at most 50 muS/cm, based on alkylene glycols or derivatives thereof and containing one or more five-membered heterocyclic compounds (azole derivatives) having 2 or 3 hetero atoms from the group consisting of nitrogen and sulfur, which contain no or at most one sulfur atom and which may carry a fused aromatic or saturated six-membered ring.

Abstract: The invention relates to an antifreeze concentrate based on alkylene glycols , glycerin, and/or 1,3-propanediol. Said antifreeze concentrate contains a) 0. 05 to 10 percent by weight, preferably 0.5 to 5 percent by weight, relative to the total quantity of the concentrate of one or several polyethylene glycols and/or polypropylene glycols, and b) 0.01 to 10 percent by weight, preferabl y 0.05 to 10 percent by weight, relative to the total quantity of the concentrate of one or several carboxylic acid amides and/or sulfonic acid amides. Ready-to-use aqueous coolant compositions containing 30 to 70 percen t by weight, especially 40 to 60 percent by weight, of the concentrate can be obtained by diluting the inventive concentrates with water. Said coolant compositions are characterized by effective corrosion inhibition of magnesiu m and magnesium alloys.

Abstract: The present invention relates to an aqueous antifreeze composition comprising 10 to 50% by weight of one or more dicarboxylic acids, preferably aliphatic dicarboxylic acids having 4 to 12 carbon atoms in the form of the alkali metal, ammonium or alkaline earth metal salt. Preferably, these salts are used in combination with at least one further substance. This gives antifreeze compositions with a good frost protective action, good heat conductivity and good protection against corrosion.
