Abstract Zeolite K-EMT is as active and selective to N-mono methylation as K–Y in the alkylation of aniline with dimethyl carbonate at 408 or 453 K. No C-alkylation occurs in the temperature range studied. At 503 K, K-X and Cs-X are about 75% selective for dialkylation to N,N-dimethylaniline with about 97% conversion.
