Abstract
New compositions, for example, corrosion inhibited compositions, and the like compositions and new methods of using such compositions are disclosed. Such compositions may be liquid solutions, for example, substantially without solid material formation and/or crystal formation, and may include different concentrations of organic acid components and/or different combinations of organic acid components relative to previous compositions. The present compositions may be used as antifreeze coolant compositions or formulations, for example, in the cooling systems of internal combustion engines.
Claims20
A corrosion-inhibited composition comprising:
- a major amount of a liquid component selected from the group consisting of water, at least one freezing point depressant and mixtures thereof;
- a t-butyl benzoic acid component in an amount in a range of about 1000 to about 35000 mg per liter of the composition;
- an azelaic acid component in an amount in a range of about 500 to about 12,500 mg per liter of the composition;
- and
- an aromatic triazole component in an amount in a range of about 100 to about 3500 mg per liter of the composition.
