Melamine trisulfonic acid catalyzed regioselective nitration of aromatic compounds under solvent-free conditions
A simple, mild and efficient method for the regioselective nitration of various aromatic compounds usingpoly(4-vinylpyridinium nitrate) (P4VPyN) in the presence of melamine trisulfonic acid (MTSA), is reported.This method provides several advantages such as good selectiveity between ortho and para positions ofaromatic compounds, clean procedure, simple work-up, short reaction times, solvent-fre...
متن کاملA Reinvestigation of Nitration of Phenols with Metal Nitrates under Non-Aqueous and Aprotic Conditions
Nitration of phenol and various 4-substituted phenols with Cu(NO3)2.3H2O, Cu(NO3)2.3H2O/SiO2, 9H2O and Cr(NO3)2. 9H2O in different anhydrous organic solvents are investigated. High selectivity ratio of para vs ortho isomers has been observed. Mono- and dinitro compounds f...
متن کاملDirect oxidative nitration of aromatic sulfonamides under mild conditions.
A direct nitration of aromatic sulfonamides using sodium nitrite as the nitrating agent has been developed. The reaction shows typically mono-substitution selectivity and can be enlarged to the gram scale with good yield.
متن کاملMaltenes and Asphaltenes of Petroleum Vacuum Residues: Physico- Chemical Characterization
Solvent separation is frequently applied to petroleum vacuum residues to reduce the coke-forming tendencies of these materials. This process is capable of removing all or a substantial amount of asphaltenes from feedstocks that are destined for further processing and thus applied as the first step of refining. Maltenes and asphaltenes obtained from vacuum residues of Heera (HVR) and Jodhpur (JV...
متن کاملMeasuring Asphaltenes and Resins, and Dipole Moment in Petroleum Fluids
A petroleum fluid can be di®ided into three types of species: asphaltenes, resins, and oils. Asphaltenes and resins are polar, while the rest of the so-called oils are either nonpolar or mildly polar. The interaction among these species strongly affect asphaltene precipitation from petroleum fluids. Different measuring methods for asphaltenes in a petroleum fluid gi®e similar results, but diffe...
