[ 1 ] - An environmentally friendly approach to the synthesis of azo dyes based on 2-naphthol using kaolin-SO3H nanoparticles
Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. The activity of this green catalyst was probed by the synthesis of aryl diazonium salts as the starting reactant and then, their diazo coupling with 2-naphthol to form azo dyes in a solvent-free medium at room temperature...

[ 3 ] - Kaolin-SO3H nanoparticles: A new efficient and reusable catalyst for synthesis of 2-substituted benzimidazoles at room temperature
Kaolinite clay found its application in medicine, in toothpaste, in cosmetic and as a food additive. Recently, a specially formulated spray is used in fruit and vegetable production to repel the insects and prevent sunburn. Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. 2-Substituted benz...
