Iranian researchers at Gilan University succeeded in the application of a new nanocatalyst as an appropriate substitute for sulphuric acid in organic reactions.
"The main problems of using acids in chemical reactions are the difficulty in the application of the known inorganic acids such as sulphuric acid, hydrochloric acid, and so on, the difficulty in the products separation, and the low yield of the products. The main purpose of this project is to synthesize and introduce a new nanocatalyst as an appropriate and effective substitute for sulphuric acid, and to use it in chemical reactions," Dr. Farhad Shirini, Chemistry Lecturer at the University of Gilan, said.
"The research was based on the chemical modification of the surface of sodium montmorillonite nanoparticles, identification of the obtained nanocatalyst, and its application as a heterogeneous nanocatalyst in various organic reactions, he said.
"The key stage in this project was to synthesize and to identify the catalyst. This stage included the surface modification of sodium montmorillonite nanoparticles by using chlorosulfonic acid, and carrying out the required tests."
Elaborating on the results of this research project, Shirini reiterated, "The initial result confirmed the synthesis and the structure of the desired catalyst through the mentioned methods. It also proved the successful application of the catalyst in speeding up the reaction to protect amines by transforming them to N-Boc derivatives."
According to the researcher of the plan, comparing the results shows that the synthesized catalyst has many advantages over the other catalysts, such as decreasing the reaction time, increasing the reaction yield, decreasing the amount of catalyst. The synthesized catalyst can also be used in a simpler way, and it facilitates the products' separation.
