PEROXY ACIDS • There are 2 types: Peroxycarboxylic acids and Peroxysulfonic acids. • Peroxycarboxylic acids are weaker acids than the corresponding carboxylic acids. • Lower peroxy acids are volatile liquids, soluble in water. • Higher acids with greater than 7 carbons are solids and insoluble in water. • These compounds are highly unstable and can decompose violently on heating. • May react dangerously with organic matter and readily oxidizable compounds. • Among organic peroxides, peroxy acids are the most powerful oxidizing compounds. • The lower acids are also shock sensitive, but less than some organic peroxides. • Health hazard primarily due to their irritant actions. Examples: Peroxyacetic acid Peroxybenzoic acid Peroxyformic acid PHENOLS • Phenols are a class of organic compounds containing hydroxyl groups attached to aromatic rings. • The hydroxyl group exhibits properties that are different from an alcoholic hydroxyl group. • Phenols are weakly acidic, forming metal salts on reactions with caustic alkalies. • In comparison, acid strengths of alcohols are negligibly small or several orders of magnitude lower than those of phenols. • In comparison with many other classes of organic compounds, phenols show relatively greater toxicity. Examples: Cresol 2-Naphthol Pentachlorophenol Phenols Resorcinol PHTHALATE ESTERS • These are esters of Phthalic acid. • They are noncombustible liquids. • Some are EPA-listed priority pollutants. • The acute toxicity is very low. 201
• High doses may produce somnolence, weight loss, dyspnea, and cyanosis. • The pure liquids are mild irritants to the skin. • These are relatively harmless and are among the least toxic organic industrial products.
