Résumé

Naphthalene is an organic chemical, with two united benzene rings. It is a residue of petroleum refining processes. It has a stable structure and is resistant to reaction. It is highly toxic and has a known negative effect on the respiratory system. In order to reduce this negative effect, we want to add a chlorine atom to its structure to turn it into mono chloronaphthalene instead of naphthalene, to be less toxic, less diffuse in the air, and nonvolatile substance. Therefore, this work aims to determine the appropriate conditions, reaction time, and most effective catalyst from the list of H3PO4, AlCl3, Al2O3, and Mo/Al2O3 under naphthalene melting temperature (80°C). Results show that Mo/Al2O3is the most effective catalyst, but after 150 minutes of reaction, AlCl3 comes next in effectiveness in the reaction time range from 60 to 150 minutes.
