Synthesis, Characterization And Catalytic Behaviour Of Entrapped Transition Metal Complexes Into The Zeolite-Y

Encapsulation of N,N-ethylenebis(salicylamide) Metal Complexes In Fly ash Based Zeolite, Characterization and Catalytic Activity

“…Similar diffraction patterns are observed for all the encapsulated complexes, except little change in the relative peak intensities. This indicates that the crystallinity of the zeolite matrix remains intact and does not suffer any major structural modifications upon encapsulation of the metal complex [31]. Due to the poor loading of the complexes during encapsulation no intense new peaks are detected [32,33] and the frame work remains intact.…”

Efficient hydroxylation of aromatic compounds catalyzed by an iron(II) complex with H2O2

“…Among various iron‐based catalysts, iron complexes have been accepted as effective homogeneous catalysts for direct hydroxylation of aromatics. In the hydroxylation of aromatic compounds in the liquid phase, O 2 and H 2 O 2 are usually used as the oxidants. The hydroxylation of aromatic compounds with H 2 O 2 is very attractive from the viewpoint of industrial technology and synthetic organic chemistry since H 2 O 2 is cheap, environmentally clean and easy to handle.…”

Characterization of ZHY and TCA/ZHY Catalysts for Hydration of α-Pinene

“…2, the relative ratio of the intensity of the line at −102 ppm to that at −108 ppm increased in the spectrum of the TCA/ZHY, suggesting that the line at −102 ppm may be partly due to the (OSi) 3 SiOH species that contains a silanol group. Thus, the line at −102 ppm is in fact an overlap of Si (1Al) and (OSi) 3 SiOH sites in the spectrum of parent ZHY. After the impregnated by the 35% TCA, the intensity of the line at −102 ppm is further increased with respect to that of the line at −108 ppm, and attains the maximum.…”
