K. Johnson et al., ALKYLATION OF TOLUENE WITH METHANOL ON MICROPOROUS MXH3-XPW12O40 [M=K+, CS+, NH4+ AND TL+], Reaction kinetics and catalysis letters, 63(2), 1998, pp. 365-370
Alkylation of toluene was carried out on microporous salts of phosphot
ungstic acid. Among the systems studied, M2.5H0.5PW12O40 showed maximu
m catalytic activity, p-Xylene selectivity was evaluated as a function
of x. A linear correlation was observed between para-selectivity and
number of strong acid sites with strength of H-0 less than or equal to
-5.6.
