Abstract
Methylamine syntheses from methanol and ammonia on various zeolite catalysts have been studied. The H-chabazite catalysts have been shown to suppress trimethylamine production almost completely, and to generate enhanced yields of monomethylamine and dimethylamine. The formation of trimethylamine has been extremely retarded, because the pore openings of the chabazite are smaller than trimethylamine molecules. The IR sorption spectra of methylamines suggest that the more bulky base molecules, such as trimethylamine, cannot penetrate into chabazite cages. The IR data suggests that the reaction proceeds with a Langmuir-Hinshelwood mechanism over the protonic sites of H-chabazite catalyst.
