Iodine was demonstrated to be an efficient catalyst for disproportionation of aryl-substituted ethers under solvent-free reaction conditions. Variously substituted 1,1,1',1'-tetraaryldimethyl ethers were transformed into the corresponding diarylketone and diarylmethane derivatives. I2-catalyzed transformation of 4-methoxyphenyl substituted ethers yielded mono- and dialkylated Friedel-Crafts pro...

Malachite green (MG) is a triphenylmethane cationic dye used in aquaculture practice, although it has been banned several countries. The illegal use by fish producers, however, persists due to its effectiveness, and ready cheap supply. To prevent indiscriminate applications, strict control measures with simple analytical approaches are therefore necessary. With this purpose, novel, method apply...

Abstract The long-term stability of aerobic granules is critical for decolourization different dyes in textile wastewater. Here, we investigated dye and the acetate-cultivated after exposure to dyes. Results show that can maintain excellent structure with presence azo triphenylmethane during a 200-day operation period, achieving biomass concentrations as high 8–12 g L−1 90% 100% efficiency, res...
