Synthesis of Hierarchical MOR-Type Zeolites with Improved Catalytic Properties
Molecules, 2021 Hierarchical MOR-type zeolites were synthesized in the presence of hexadecyltrimethylammonium bromide (CTAB) as a porogen agent. XRD proved that the concentration of CTAB in the synthesis medium plays an essential role in forming pure hierarchical MOR ...

Mechanochemical Birch Reductive Alkylation of Polycyclic Aromatic Hydrocarbons
ChemistryEurope, Volume 4, Issue 10, October 2026.A lithium‐mediated mechanochemical Birch reductive alkylation enables the direct alkylation of unfunctionalized PAHs with readily available alkyl fluorides. Various primary‐ and secondary‐alkylated PAHs are obtained by an easy‐to‐operate one‐pot and two‐step procedure including ball‐milling PAHs with Li wire and addition of alkyl fluorides at room ...

The Canadian Journal of Chemical Engineering, Volume 104, Issue 10, Page 5267-5282, October 2026.Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.
