Influence of reaction products on the selective oxidation of ethene [PDF]

open access: yes, 1996
The kinetics of the selective oxidation of ethene in air over an industrial silver on ¿-alumina catalyst were studied. Special attention was paid to the influence of the reaction products on the reaction rates of epoxidation and complete combustion ...

Titanium cis-DACH Salan Catalyst for the Efficient Epoxidation of Nonactivated Olefins with Hydrogen Peroxide-Terminal-Selective Epoxidation of Multiply Unsaturated Terpenes. [PDF]

open access: yesChemistry
Terminal‐selective epoxidation–catalytic, simple, and with H2O2 as oxidant. The titanium complex of a new type of salan ligand, accessible in one step from cis‐DACH and 3‐(pentafluorophenyl)salicylic aldehyde, is an efficient catalyst for the epoxidation of nonconjugated olefins with H2O2.

Epoxidation of Terpenes [PDF]

open access: yesCatalysts, 2021
Terpene epoxides are considered as potential primary intermediates in the synthesis of numerous green polymers including epoxy resins, polycarbonates, nonisocyanate polyurethanes and even some polyamides. In this chapter we describe recent efforts from our group to develop catalytic and noncatalytic processes for terpene epoxidation using a variety of ...
