J. Rakoczy, EFFECT OF METHANOL CONCENTRATION ON SUBSTRATE CONVERSION IN ALKYLATION OF TOLUENE ON ZEOLITE CATALYSTS, Reaction kinetics and catalysis letters, 48(2), 1992, pp. 401-409
Influence of the concentration of toluene and methanol on the substrat
e conversion in toluene methylation reaction was studied by a pulse me
thod. Increased methanol partial pressure gave better conversion to xy
lenes whereas toluene partial pressure did not affect the reaction. Th
is behavior has been interpreted by supposing that the first step in t
oluene methylation is chemisorption of methanol on zeolite.
