Physical properties White crystalline solid; unstable, decomposes at 45°C; commercial product is a syrupy liquid containing equal parts of Caro’s acid and sulfuric acid; stored at dry ice temperature; very soluble in water.
Uses peroxomonosulphuric acid (Caro's acid) is used in the preparation of dyes and bleaching agents. It also is used as a strong oxidizing reagent to convert ketones to lactones, to convert olefins to glycols and esters, and to analyse pyridine, aniline and many alkaloids. In preparation of dyes; oxidation of olefins to a-glycols; oxidation of ketones to lactones or esters; treating woolens to prevent felting and shrinking; in bleaching compositions. Peroxymonosulfuric acid is used as an oxidizingagent to make glycols, lactones, and esters; formaking dyes; and in bleaching composition.
