Applicazioni

Sodium percarbonate is used as an oxidizing agent and environmentally friendly bleaching agent. It is used as a laboratory source of anhydrous hydrogen peroxide. It is utilized for the preparation of optically active 4-hydroxy-2-isoxazolines. It is widely used in detergent formulations and cleaning products such as carpet cleaner, textile bleach, denture cleaners, pulp and paper bleaching processes. It is also used as a hard filth removing agent in electroplating, waste water treatment agent and polymerization control agent. Further, it finds application in furniture polish and cleaners and personal care formulations. In addition to this, it is used in the preparation of trimethyl cyclopentenyl acetaldehyde and epoxydihydrolinalool.

Note

Moisture sensitive. Incompatible with strong reducing agents, strong acids, organic materials and powdered metals.

Has been used in the presence of a catalytic amount of Pyridinium dichromate, L15132, or Potassium dichromate, A18722, and a phase-transfer catalyst, for the selective oxidation of secondary alcohols to ketones: Tetrahedron Lett., 35, 1989 (1994); Synth. Commun., 25, 2373 (1995).

Can be used to generate the powerful oxidant peroxytrifluoroacetic acid from trifluoroacetic anhydride, avoiding the use of hazardous 90% hydrogen peroxide. The in situ generated peracid is useful in promoting the Baeyer-Villiger reaction of difficult substrates: Bull. Korean Chem. Soc., 17, 5 (1996).
