Dendritic ZSM-5 zeolites were investigated in the isomerization of monoterpene epoxides, including limonene-1,2-epoxide (LE), α-pinene epoxide, and β-pinene epoxide, which yields high-value compounds used in fragrances, cosmetics, and pharmaceuticals. The fresh catalysts were thoroughly characterized using XRD, Ar physisorption, pyridine-FTIR, TEM,...
This study explores the isomerization of limonene-1,2-epoxide (LE) from kinetic and mechanistic viewpoints, using a dendritic ZSM-5 zeolite (d-ZSM-5) as a highly selective catalyst for the formation of dihydrocarvone (DHC) in the form of diastereoisomers (cis + trans).

The highest selectivity to pyranols, 70% was obtained over micropo...
Parent, hierarchical, and metal-modified hierarchical zeolite Y were investigated as heterogeneous catalysts in the R-(+)-limonene epoxidation, a catalytic route for synthesizing precursors of bio-polycarbonates, an alternative to isocyanate polyurethanes. The fresh catalysts underwent detailed characterization using XRD, N2 physisorption, TEM, SEM...
The products obtained from limonene epoxidation can be used as intermediates or precursors in organic and pharmaceutical synthesis. Commercial magnesium oxide was evaluated as a heterogeneous catalyst in the epoxidation of R-(+)-limonene using H2O2 in a Payne reaction system, using acetonitrile as an oxidant activator and water and acetone as solve...
A Preyssler-type heteropolyacid supported on silica, synthesized and characterized by FTIR, was tested for levulinic acid (LA) esterification with n-butanol under microwave-assisted batch reaction conditions. The optimal conditions were found to be 40 mg of catalyst, a 5:1 n-butanol/LA molar ratio at 160 °C and 3 h, resulting in 77% conversion with...
Beta-Pinene is one of the main components of turpentine oil, which can be extracted from different Pinus species. In this way, the study of its valuation towards high added-value products such as myrtanal is a significant challenge in fine chemistry. In the present work, MCM-41 was synthesized according to the traditional methodology using the sol-...
A kinetic study, based on Langmuir-Hinshelwood-Hougen-Watson (LHHW) and Eley-Rideal (ER) approaches, was developed to describe the esterification reaction of trans-cinnamic acid and n-butanol over heterogeneous catalysts.
