In this article, the sulfuric acid supported on the graphene oxide@ZIF-90 composite functionalized with ethylenediamine (GZAH) was synthesized and characterized with FTIR, SEM, TEM, EDS, BET, and TGA. Then, the synthesis of some sulfonamides was performed using the as-prepared nanocatalyst via N-acylation reaction. FTIR, 1HNMR, 13CNMR, and CHNS techniques were used to identify organic mols. The best results (93% yield) were obtained using a catalyst (0.1 g) in acetonitrile as a solvent and for 2 h at 60°C. The catalyst was recycled up to 5 times, maintaining efficiency. In the part of experimental materials, we found many familiar compounds, such as 4-Methylbenzenesulfonamide(cas: 70-55-3Quality Control of 4-Methylbenzenesulfonamide)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. Primary amines having a tertiary alkyl group (R3CNH2) are difficult to prepare with most methods but are made industrially by the Ritter reaction. In this method a tertiary alcohol reacts with hydrogen cyanide (HCN) in the presence of a concentrated strong acid; a formamide, RNH―CHO, is formed first, which then undergoes hydrolysis.Quality Control of 4-Methylbenzenesulfonamide
