    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 invention relates to a thermal liquid concentrate containing a glycol an d: a) 0.05 to 10 percent by weight, preferably 0.1 to 5 percent by weight, of o ne or several aliphatic amines of general formula (I), wherein R1 to R3 can be identical or different and represent hydrogen, optionally branched C1-C9alky l, or C1-C9 hydroxyalkyl; b) 0.005 to 3 percent by weight, preferably 0.01 to 1 percent by weight, of one or several optionally stabilized silicates; c) 0 t o 3 percent by weight of one or several corrosion inhibitors selected among th e group comprising hydrocarbon triazoles and hydrocarbon thiazoles; d) 0 to 5 percent by weight of one or several alkali metal molybdates, ammonium molybdates, or substituted ammonium molybdates; and e) 0 to 1 percent by weight of one or several polymeric hard water stabilizers. The inventive concentrates are particularly suitable for use in solar systems after being optionally diluted with water, thermal liquid being in direct contact with t he glass of the solar system.
