    摘要： 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.

    摘要： An antifreeze concentrate based on alkylene glycols, glycerol and/or 1,3-propanediol comprises a) from 0.05 to 10, preferably from 0.5 to 5, % by weight, based on the total amount of the concentrate, of one or more polyethylene glycols and/or polypropylene glycols and b) from 0.01 to 10, preferably from 0.05 to 10, % by weight, based on the total amount of the concentrate, of one or more carboxamides and/or sulfonamides. Ready-to-use aqueous coolant compositions which contain from 30 to 70, in particular from 40 to 60, % by weight of the concentrate are obtainable from the novel concentrates by dilution with water. Said compositions are distinguished by effective corrosion inhibition in the case of magnesium and magnesium alloys.
