A process for the production of nitroarenes with high para-selectivity from monosubstituted aromatic hydrocarbons using aluminosilicates as catalysts |
摘要 |
The present invention relates to a process for the production of nitroarenes with high para-selectivity from monosubstituted aromatic hydrocarbons using aluminosilicates as catalysts, which comprises nitration of monosubstituted aromatic hydrocarbons using aluminosilicates of different ratios wherein Si/Al ranges between 5 to 1000 and the said aliminosilicates being manifested in the form of variety of zeolites and K10 montmorillonite as catalysts using nitric acid in the molar ratio of nitric acid to monosubstituted aromatic hydrocarbons ranging between 0.25 to 2.5 at a temperature in the range of 30-160 DEG C for a period ranging between 0.25 to 3.0 h and followed by continuous removal of water formed from the reaction mixture with a Dean-Stark apparatus and recovery of the product mixture by concentration of the reaction mixture after separation of the catalyst by filtration. |
