Vapor phase alkylation of toluene using various alcohols over H3PO4/MCM-41 catalyst: influence of reaction parameters on selectivity and conversion
Alkylation toluene mesoporous MCM-41 vapor phase H3PO4
2010/12/20
A mesoporous MCM-41 molecular sieve material with a molar ratio of SiO2/Al2O3 = 70 and loaded with H3PO4 was used as a catalyst for the alkylation of toluene, using various alcohols, namely methanol, ...

A novel chemiluminescence(eL)sensor for gallic acid combined flow—injection analysis was presented．The analytical reagents involved in the CI reaction，including luminol and ferricyanide，were both immo...
Polarization Selectivity of Third-Order and Fifth-Order Raman Spectroscopies in Liquids and Solids
Polarization Selectivity Third-Order and Fifth-Order Raman Spectroscopies Liquids and Solids
2014/9/24
Polarization selectivity of third-order and fifth-order Raman spectroscopies is examined for both isotropic liquids and periodic lattices. Our approach directly applies the symmetry property of the pr...
