Alkylation of aniline (PhNH2) with methanol (MeOH) over cocrystallized zeolite RHO-zeolite X (FAU) and over zeolite Linde type L (Sr,K-LTL) as catalysts has been studied. Cocrystallized zeolite RHO-zeolite X (FAU) favors the formation of N,N-dimethylaniline (NNDMA) with high selectivity > 90%, having an advantage over pure zeolite X (FAU) of staying active even after 10 h of reaction. Activity of cocrystallized RHO-zeolite X (FAU) is higher than that for Sr,K-LTL in terms of the production of N,N-dimethylaniline.
