Abstract: | (Laex, Na)-X, FAU, (Na, Yex)-X, FAU, (Laex, Na)-Y, FAU and (Na, Yex)-Y, FAU have been shown to be active and selective catalysts for the alkylation of toluene with methanol. Na–X, FAU and Na–Y, FAU modified by La3+ have the highest activity but a very stable activity was reached only on Y3+ forms. (Na, REex)-X FAU series prefer ortho-substitution while (Na, REex)-Y, FAU para-substitution. Brönsted acid centers and their strength are responsible for substition.
