Abstract

Boehmite is a cubic orthorhombic structure of aluminum oxide hydroxide, which prepared via addition of sodium hydroxide solution to an aluminum nitrate solution at room temperature. In this work, the surface of boehmite nanoparticles (BNPs) modified by 3-choloropropyltrimtoxysilane (3-CPTMS), then reacted with N,N,N′,N′-tetraethyldiethylentriamine (TEDETA). Eventually, CuI immobilized on modified boehmite (CuI-TEDETA@BNPs). Structure of this catalyst was characterized using FT-IR, TEM, SEM, EDS, TGA, and AAS techniques. Finally, the catalytic activity of CuI-TEDETA@BNPs was studied for the synthesis of ethers and sulfides. All ethers and sulfides were obtained in high yields, which reveals the high activity of described catalyst. This catalyst was reused for several times without significant loss of its catalytic efficiency. Recovered catalyst was characterized by SEM and FT-IR techniques, which shown a good agreement with fresh catalyst. Also, heterogeneity and stability of CuI-TEDETA@BNPs confirmed by hot filtration test.
