Abstract: Aqueous coolant with good corrosion inhibition comprises a phthalic acid monoamide ammonium salt. Aqueous coolant comprises a phthalic acid monoamide ammonium salt of formula (I); R1 and R2 = H or 1-20C alkyl; and A+ = ammonium cation. Independent claims are included for: (1) a cooler protectant concentrate comprising (I); and (2) the use of (I) in aqueous coolants for combustion motors.

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.
