Abstract

An aqueous liquid aircraft runway deicer composition having minimal catalytic oxidation effect upon carbon-carbon composites which contains between about 20 and about 25 weight % of an alkaline earth metal carboxylate, between about 1 and about 15 weight % of an alkaline earth metal carboxylate, between about 1 and 35 weight % of an aliphatic alcohol, between about 0.01 and about 1 weight % of an alkali metal phosphate, between about 0.01 and about 1 weight % of an alkali metal silicate, and up to about 1% by weight of a triazole. A process for producing such a liquid aircraft runway deicer blends an alkali metal hydroxide, an alkali metal phosphate and an alkali metal silicate in aqueous solution and reacts a carboxylic acid with the hydroxide in the solution to create an alkali metal carboxylate solution at a pH of about 14.2. A minor amount of a triazole is added when the pH is below 15. An aqueous slurry of an alkaline earth metal oxide or hydroxide is reacted with a carboxylic acid to create an aqueous solution of alkaline earth metal carboxylate. These two solutions are blended with an aliphatic alcohol to produce an effective liquid runway deicer having minimal catalytic oxidation effect upon carbon-carbon composites.
