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...
متن کاملNitration of naphthalene and remarks on the mechanism of electrophilic aromatic nitration.
Naphthalene was nitrated with a variety of nitrating agents. Comparison of data with Perrin's electrochemical nitration [Perrin, C. L. (1977) J. Am. Chem. Soc. 99, 5516-5518] shows that nitration of naphthalene gives an alpha-nitronaphthalene to beta-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant. Perrin's data, therefore, are considered to be inconclusive evidence...
متن کاملTransmembrane nitration of hydrophobic tyrosyl peptides. Localization, characterization, mechanism of nitration, and biological implications.
We have shown previously that peroxynitrite-induced nitration of a hydrophobic tyrosyl probe is greater than that of tyrosine in the aqueous phase (Zhang, H., Joseph, J., Feix, J., Hogg, N., and Kalyanaraman, B. (2001) Biochemistry 40, 7675-7686). In this study, we have tested the hypothesis that the extent of tyrosine nitration depends on the intramembrane location of tyrosyl probes and on the...
متن کاملMitochondria and regulated tyrosine nitration.
The conditions of the cellular microenvironment in complex multicellular organisms fluctuate, enforcing permanent adaptation of cells at multiple regulatory levels. Covalent post-translational modifications of proteins provide the short-term response tools for cellular adjustment and growing evidence supports the possibility that protein tyrosine nitration is part of this cellular toolkit and n...
متن کاملProtein nitration in cardiovascular diseases.
There is growing evidence that cardiovascular disease is associated with progressive changes in the production of free radicals and radical-derived reactive species. These intermediates react with all major cellular constituents and may serve several physiological and pathophysiological functions. The nitration of protein tyrosine residues has been used as a footprint for in vivo production of ...
