With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter

Chemical Formula: ClC6H4CO3H
Molar Mass: 172.57 g/mol
Synonyms: 3-Chloroperoxybenzoic acid, meta-Chloroperbenzoic acid, MCPBA

General description

3-Chloroperbenzoic acid is a strong oxidizing agent mainly used for the epoxidation of alkenes and also in the Baeyer-Villiger oxidation of ketones to esters.

Application

3-Chloroperbenzoic acid has been used in the oxidation of N–p-tolylsulfinyl-(E)-1-phenylethylideneimine to N–p-tolylsulfonyl (E)-1-phenylethylideneimine using dichloromethane as a solvent. It has also been used in the preparation of mono- and di-epoxy-functionalized poly(3-hydroxybutyrate)-based reactive polymers. MCPBA is also an effective oxidizing agent for the conversion of α-amide substituted polyesters to their corresponding polysulfones with tunable thermal properties.

Effective oxidant for epoxidizing di-, tri-, and tetra-substituted olefins.

Benzene is a six-membered aromatic compound that can undergo ionization induced by superhalogens, according to ab initio calculations. This compound is a frequently used industrial solvent but is also considered an air pollutant and a powerful carcinogen.

Benzene may be used in the formation of phenyl acetate by aerobic oxidation using Pd catalyst and acetic acid as solvent, formation of phenol by hydroxylation in the presence of mesoporous carbon nitride supported on vanadium catalyst and as a solvent to prepare nanoparticles of gallium nitride (GaN) by reacting Li3N and GaCl3 at 280°C.
