Abstract
Non-silicate, non-gelling corrosion inhibited antifreeze compositions containing a water-soluble liquid alcohol freezing point depressant and an inhibitor combination comprising an alkali metal salt of benzoic acid, an alkali metal salt of a dicarboxylic acid and an alkali metal nitrate are described. These formulations work just as well or better than silicate-based formulations in all regards and have the advantage of not having to contain expensive organo silane gellation inhibitors as do silicate-containing antifreezes. The dicarboxylic acid used preferably has eight to twelve carbon atoms.
