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...

متن کاملMechanistic studies of the molybdenum-catalyzed asymmetric alkylation reaction.
Enantiomerically enriched, deuterated branched carbonates (Z)-(S)-PhCH(OCO(2)Me)-CH = CHD (1-D), (Z)-(R)-PhCH(OCO(2)Me)CH = CHD (2-D), and linear carbonate (E)-(S)-PhCH = CHCHD(OCO(2)Me) (3-D) were used as probes in the Mo-catalyzed asymmetric allylic alkylation with sodium dimethyl malonate, catalyzed by ligand-complex 11 derived from the mixed benzamide/picolinamide of (S,S)-transdiaminocyclo...
متن کاملEvolutionary Computation Strategy for Optimization of an Alkylation Reaction
The alkylation process is an important reaction used in refineries to upgrade light olefins and isobutene into a much more highly valued gasoline component. The primary alkylation reaction involves the reaction of isobutene with a light olefin such as butylenes, in the presence of strong acid catalyst to form the high octane. A problem of long standing is to determine the optimal operating cond...
متن کاملApplication of GA in Optimization of Modified Benzene Alkylation Process
A genetic algorithm is used to optimize the modified benzene alkylation process. Based on the previous studies, the modified process increases ethylbenzene selectivity and decreases energy consumption at the same time. The inlet ethylene flow rate of each alkylation reactor is optimized in order to reduce the chance of transalkylation reactions but increase ethylbenzene selectivity. The byprodu...
