Abstract
Alkylation of toluene was carried out on microporous salts of phosphotungstic acid. Among the systems studied, M2.5H0.5PW12O40 showed maximum catalytic activity.p-Xylene selectivity was evaluated as a function of x. A linear correlation was observed betweenpara-selectivity and number of strong acid sites with strength of H0≤−5.6.
