Used as a strong acid catalyst in organic synthesis, particularly in esterification, etherification, and alkylation reactions. Commonly applied in the production of biodiesel, where it catalyzes the transesterification of triglycerides with methanol. Also utilized in hydrolysis reactions and removal of acidic impurities due to its high ion-exchange capacity. Its heterogeneous nature allows for easy separation and reuse in industrial processes, making it ideal for continuous flow systems. Stable under high temperature and pressure, it is favored in petrochemical and fine chemical industries for efficient and environmentally friendly catalysis.
