Re-synthesis of malachite green

In this research work, we obtained a dye that is mainly used in the industry of textile it is also used in aquaculture as an antifungal, antiparasitic, antibacterial and therapeutic agent. For having a good yield we tried to design simple and better working conditions. It was determined the best conditions for the catalyst. By using SnCl4 as a catalyst we had a better yield than other catalysts used before also the temperature at which reaction was carried out is low, and the time reaction is also short. Catalysts, solvent used in reaction, the molar ratio of reactants and the time reaction is done were the main parameters that leded to the establishment of optimal synthesis conditions.
