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, ...
Development of a New Set of Additive Parameters for the Estimation of Geometrical Distortion of Cycloalkanes from C-13 NMR Chemical Shifts
Additivity parameters C-13 NMR chemical shifts geometrical distortion cycloalkanes
2010/4/16
A previous model for the calculation of C-13 chemical shifts is modified by replacement of 3 parameters representing the p-character of carbon atom in cyclic systems with a single parameter aiming for...
