Cationic yellow X-8GL generation method：

Cationic yellow X-8GL takes ω-aldehyde and p-aminoanisole as the main raw materials, through condensation, salt formation, filtration and drying to obtain finished products. . The latest research shows that water can be used as a solvent for the synthesis reaction, and a phase transfer catalyst can be added at the same time to make the reaction proceed smoothly, with a yield of 94%.
