Unveiling the Roles of Ti Species and Solvent in Propylene Epoxidation With H2O2 Over Titanosilicate‐1 Catalyst Through Density Functional Theory Insights

Carbon and Hydrogen, Volume 28, Issue 2, Page 269-283, June 2026.
This work employs density functional theory (DFT) calculations to identify the reaction mechanism and unveil the roles of Ti species and solvent in propylene epoxidation with H2O2 over TS‐1 catalyst. ABSTRACT The mechanism of propylene epoxidation catalyzed by distinct titanium (Ti) species within the TS‐1 framework was systematically explored through ...

Reprocessable and Repairable Bio‐Based Vitrimers From Acrylated Epoxidized Rapeseed Oil for Additive Manufacturing

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
Bio‐based UV‐curable vitrimer resins derived from acrylated epoxidized rapeseed oil enable reprocessable and repairable thermosets for vat photopolymerization. Catalyst‐free and Zn‐based systems reveal tunable stress relaxation and mechanical recovery. Remarkably, repaired 3D‐printed parts exceed original strength, highlighting dynamic bond exchange as

Metathesis‐Sourced Epoxides in Ring‐Opening Copolymerization: Selective Access to Degradable Polythioesters

Macromolecular Rapid Communications, Volume 47, Issue 11, 5 June 2026.
Metathesis‐derived cyclopentene epoxides enable strictly alternating, scrambling‐free ring‐opening copolymerization with phthalic thioanhydride, yielding well‐defined polythioesters with molecular weights up to ∼38 kg/mol. Their performance extends to oxygen‐based anhydrides and selective terpolymerizations. Direct comparisons with all‐oxygen analogues

Micro–Mesoporous Ferrierite: Strategies for Tuning the Accessibility of a Peculiar Zeolite

ChemCatChem, Volume 18, Issue 10, 27 May 2026.
The anisotropic structure of ferrierite (FER) zeolite makes challenging the increase of catalyst effectiveness by hierarchical porosity. The pore mouth location of the active sites for butene isomerization requires a fine balance between development of external surface and retention of shape selectivity.

Epoxidation of propene in a confined Taylor flow (CTF) reactor at atmospheric pressure [PDF]

, 2017
Heterogeneous catalytic epoxidation of propene to propene oxide with hydrogen peroxide as oxidant was investigated in a confined Taylor flow (CTF) reactor, a continuous monolith reactor, containing a long alumina rod coated with titanium silicalite (TS-1)

Gold catalysts for liquid phase epoxidation of terminal alkenes: 1-decene and propene [PDF]

Gold surfaces have long been regarded as inert and poor catalyst due to their highly stable chemical structures; nevertheless, it has been demonstrated that gold becomes extremely catalytically active when sizes are reduced to < 15 nm and synthesis are
