Environmentally benign process for benzylation of toluene to mono-benzylated toluene over highly active and stable hierarchical zeolite catalyst

Highly regioselective dinitration of toluene over reusable zeolite H

Catalytic Transformation of Toluene over High Acidity Y-Zeolite Based Catalyst

Catalyst S. Al-Khattaf* Chemical Engineering Department, King Fahd University of Petroleum & Minerals Dhahran 31261, Saudi Arabia Abstract Catalytic transformation of toluene has been investigated over Y-zeolite based catalysts in a novel riser simulator at different operating conditions. A number of experiments were carried out in the temperature range of 400-500C to understand the transformat...

Hierarchical mesoporous TS-1 zeolite: a highly active and extraordinarily stable catalyst for the selective oxidation of 2,3,6-trimethylphenol.

We report the synthesis of a new hierarchical mesoporous TS-1 type zeolite by a simple steam-assisted crystallization method. This novel product exhibits high catalytic activity and a strongly prolonged lifetime in the selective oxidation of 2,3,6-trimethylphenol to trimethyl-p-benzoquinone.

Hierarchical mesoporous TS-1 zeolite: a highly active and extraordinarily stable catalyst for the selective oxidation of 2,3,6-trimethylphenolw

The selective oxidation of 2,3,6-trimethylphenol (TMP) is of great importance for the preparation of 2,3,5-trimethyl-pbenzoquinone (TMBQ), a key intermediate in the production of Vitamin E. Various oxidant/catalyst, such as O2 or H2O2/CuCl2 (especially with various co-catalysts) have been employed in this oxidation process on the industrial scale. However, the main drawback of the above-mention...

Zeolite catalyzed alkylation of toluene by alcohol

Vapor-phase methylation of toluene using methanol and its isopropylation with 2-propanol has been investigated ina down flow reactor under atmospheric conditions using N2 carrier over a series of surface modified andunmodified ZSM-5 (Si/Al= 60-170) loaded with H3PO4, differing in the external surface treatment of the zeolites.The feed molar ratios of toluene/methanol and toluene/2-propanol were...
