Methylamines, including monomethylamine (MMA), dimethylamine (DMA), and trimethylamine (TMA), are essential industrial intermediates. However, traditional catalysts suffer from poor product selectivity being phased out due to shifting market demands. Zeolites have emerged as promising alternatives their high activity superior selectivity. Large- medium-pore zeolites require modifications enhance MMA- DMA-selectivity by reducing pore size, whereas small-pore inherently exhibit for MMA DMA without modification. production costs hindered large-scale commercialization. Research efforts now focused on developing cost-effective shift methylamine synthesis equilibrium-driven (balancing) selective (unbalancing) processes. This review explores the performance of zeolite-based in synthesis, highlighting key factors influencing Additionally, it examines challenges associated with discusses strategies application.
