TL;DR: In this paper, the similarities and specificities of the transformation of cyclohexane into adipic acid (via the formation and isolation of the cycloshexanol-cyclohexanone mixture) and of the process for the preparation of terephthalic acid by oxidation of p-xylene are analysed from a prospective viewpoint.

TL;DR: In this article, a short review of the development of catalysts for epoxidations and for carbon-carbon bond cleavage is presented, focusing on fully inorganic systems, some with the dimeric moiety [M2O2(μ-O2)2(O2 )2], (M = V, Mo, W) which have more scope than those containing organic ligands or supports.

TL;DR: In this paper, two titanium silicalite-1 samples (A and B) with similar particle sizes have been characterized by powder X-ray diffraction, FT-IR and FT-Raman spectroscopy, UV-visible diffuse reflectance spectroglobalization (DRS), transmission electron microscopy with Xray energy dispersion spectrometry (to analyze grains and ultramicrotomed sections), and xenon-129 NMR.

TL;DR: In this article, an original pathway for the reaction between low-cost Mo(VI) peroxo species and silica precursors (tetraethylorthosilicate), silica beads (pure SiO2) or precipitated silica in an acidic and peroxidic medium (peroxo route).

TL;DR: In this article, two sets of WOx/SiO2-MCM-41 precatalysts (A and B) were prepared and compared, and the results suggest that the novel preparation method (route A) has a marked effect on the dispersion of the WOx species on and into the silica matrix.
