Abstract

Process for obtaining refined naphthalene from technical naphthalene, in particular that obtained from the chemistry of coal, by means of the sequential combined application of stages of selective catalytic hydrogenation, acid-base extraction and fractional distillation which make it possible to provide customised treatment for each of the impurities present in the technical naphthalene. Application in the chemical and pharmaceutical industry.
