An improved route involves the reaction of chromyl chloride and potassium chromate:[5] The salt consists of the tetrahedral chlorochromate anion.
[6] Although air-stable, its aqueous solutions undergo hydrolysis in the presence of strong acids.
[7] Peligot's salt can oxidize benzyl alcohol, a reaction which can be catalyzed by acid.
[8] A related salt, pyridinium chlorochromate, is more commonly used for this reaction.
Potassium chlorochromate is toxic upon ingestion, and may cause irritation, chemical burns, and even ulceration on contact with the skin or eyes.
