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.
Definition
ChEBI: Peroxysulfuric acid is a sulfur oxoacid. It is a conjugate acid of a peroxysulfate(1-).
Health Hazard
Peroxymonosulfuric acid is a strong irritant to theskin, eyes, and mucous membranes (Merck 1989).Toxicity data for this compound are not available.
Fire Hazard
Peroxymonosulfuric acid is highly unstable, decomposes dangerously on heating, and evolves oxygen at room temperature. It may react violently with organic matter and readily oxidizable compounds. Violent explosions have been reported with acetone, due to the formation of acetone peroxide (Toennis 1937). It may explode when mixed with many primary and secondary alcohols, manganese dioxide, cotton, many metals in finely divided form, and aromatics such as benzene, phenol, and aniline.
Safety Profile
Strong irritant. Powerful oxidizer. An explosive. Explosive reaction acetone; alcohols; aromatics (e.g., aniline; benzene; phenol); platinum; manganese dioxide; silver. Incompatible with acetone; catalysts; fibers. When heated to decomposition it emits t
