This article studies the synthesis of 1-naphthylacetic acid between naphthalene and monochloroacetic acid in the presence of an aluminum-based catalyst. The reaction is carried out at high temperature, where aluminum activates monochloroacetic acid to form a reactive carbocation intermediate. This intermediate is added to the α-position of naphthalene via an electrophilic substitution reaction, and upon hydrolysis forms 1- naphthylacetic acid. The final product is characterized by melting point, IR spectrum and chromatographic methods. This method is proposed as a simple, efficient and raw material-rich synthesis route that can be applied in industrial conditions. Keywords: 1-Naphthylacetic acid, monochloroacetic acid, naphthalene, electrophilic aromatic substitution, aluminum catalyst
