Copper(II) complexes with new polypodal ligands presenting axial-equatorial phenoxo bridges {2-[(Bis(2-pyridylmethyl)amino)methyl]-4-methyl phenol, 2-[(Bis(2-pyr1dylmethyl)amino)methyl]-4-methyl-6-(methylthio)phenol}: Examples of ferromagnetically coupled
(2007)
Two new ligands, 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenol (HL) and 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methyl-6-(methylthio)phenol (HSL), were synthesized and were used to prepare the trinuclear copper(II) ...
Phenol methylation on acid catalysts: Study of the catalyst deactivation kinetics and mechanism
(Elsevier Science, 2014-01)
The kinetics and mechanism of coke formation and catalyst deactivation during the synthesis of cresols from phenol methylation were investigated on SiO2–Al2O3, tungstophosphoric acid (HPA) supported on silica, and zeolites ...
Study of Gas Phase m-Cresol Alkylation with Methanol on Solid Acid Catalysts
(Springer, 2014-09)
The gas-phase alkylation of m-cresol with methanol was studied at 523 K on Al-MCM-41 and zeolites ZnY, HBEA, HZSM5 and HMCM22. The acidity was determined by ammonia TPD and FTIR of adsorbed pyridine.On acid sites of moderate ...

Study of the alkylation of phenol with methanol on Zn(H)-exchanged NaY zeolites
(Springer, 2011-07)
The gas-phase alkylation of phenol with methanol was studied at 473 K on zeolite NaY exchanged with Zn+2 (samples Zn(x)NaY) or H+ (samples Na(x)HY) cations. Zeolite NaY contained only weak and medium Lewis acid sites. The ...
