Refined naphthalene can be used in the production of phthalic anhydride, intermediate of dyes, rubber auxiliaries and insecticides. Naphthalene can be divided into industrial naphthalene and refined naphthalene according to its purity. The purity of industrial naphthalene is generally about 96%. After further purification of industrial naphthalene and removal of impurities and desulfurization, high purity of refined naphthalene can be obtained.
