    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.
