Eco-friendly Method for Nitration of Aromatics

Eco Friendly Nitration of Toluene using Modified Zirconia

Nitration of toluene has been studied in the liquid phase over a series of modified zirconia catalysts. Zirconia, zirconiaceria (Zr0.98Ce0.02)O2, sulfated zirconia and sulfated zirconiaceria were synthesised by co precipitation method and were characterised by X-ray diffraction, BET surface area, Infra red spectroscopy analysis (FTIR), Thermogravimetric analysis (TGA), Scanning Electron Microsc...

Nucleophilic Nitration of Selected Aza-aromatics: Experiments and Modelling

Nitration of isoquinoline and phthalazine has been successfully demonstrated using a novel process which does not require strong acids. In this study, nitration of isoquinoline was repeated and the method applied to 1-nitroisoquinoline and the azaaromatics quinoline, quinazoline, quinoxaline and pyridine. Nitration of only quinoline was observed, with a product yield lower than that reported fo...

Recommending Eco-Friendly Route Plans

As personal transportation is one of the greatest contributors of CO2 emissions, means able to assist travelers in reducing their ecological impact are urgently needed. In this work we focus on travel recommenders that encourage green transportation habits among travelers who have a preexisting interest in taking action to lessen their impact on the environment. We aim to provide urban traveler...

A green and eco-friendly method for the synthesis of xanthene derivatives using cellulose sulfuric acid under solvent-free conditions

A green and convenient method for the synthesis of 14-aryl-14H-dibenzo[a,i]xanthene-8,13-diones and spiro[dibenzo[a,i]-xanthene-14,3'-indoline]-2',8,13-triones in the presence of a catalytic amount of cellulose sulfuric acid (CSA) as an efficient biopolymer-based catalyst under solvent-free conditions at 100 °C is described. The condensation reactions of β-naphtol, 2-hydroxynaphthalene-1,4-dion...
