General description

Heterogeneous ozonolysis of naphthalene adsorbed on XAD-4 resin has been studied using annular denuder technique.

Naphthalene is widely used to synthesize naphthylamines,sulfonic acid,synthetic resins,anthranilic and phthalic acids.

Application

Naphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets. It was used in preparation of carbon-coated Si70Sn30 nanoparticles. It was used as fluorescent probe to study the aggregation behavior of sodium cholate.
