Epoxidation of Styrene over a Titanium Silicate Molecular Sieve TS1 Using Dilute H2O2 as Oxidizing Agent

A novel copper(II) complex bearing salicylaldimine immobilized on SBA-15 and its catalytic performances in styrene oxidation by hydrogen peroxide

“…On the other hand, the selectivity to benzaldehyde was improved to 28.6% when the temperature decreased to 60°C. It is worth pointing out that the lower temperature benefits benzaldehyde, which is in accordance with the catalytic performances of TS-1 reported by Kumar et al [27]. It is interesting that reaction parameters influence the activity to a certain degree, but have little effect on product distributions.…”

Oxidative Cleavage of C=C Bond of Styrene and Its Derivatives with H2O2 using Vanadyl (IV) Acetylacetonate Anchored SBA-15 Catalyst

“…From this study, it is found that the optimum amount of the catalyst is 50 mg. Similar observation put forward by Maurya et al [39] over zeolite encapsulated Cu(II) complex catalyst.…”

“…Additionally, three oxygenates, such as (i) styrene epoxide (Epoxide), (ii) 1-phenylethane-1, 2-diol (Diol) and (iii) benzoic acid (Acid) were detected in the product mixture. The formation of the above cited four products is quite common in the oxidation of styrene both on homogeneous and heterogeneous catalytic systems [39,40].…”

Rapid and Highly Selective Epoxidation of Styrene by meta-Chloroperbenzoic Acid Catalyzed by Manganese Meso-tetrakis(Pentafluorophenyl)Porphyrin in the Presence of Tetrabutylammonium Acetate and Bromide

“…Among olefins epoxidation of styrene to styrene oxide is of particular interest from both scientific and commercial point of view [15,16]. However the formation of desired product (styrene oxide) is always accompanied by the oxidative cleavage of double bond to benzaldehyde and isomerisation of styrene oxide to phenyl acetaldehyde [17,18]. Achieving high selectivities, excellent yields and mechanism elucidations are of interest for these catalytic epoxidations.…”
