    摘要: A boron-containing molecular sieve having the CHA crystal structure and comprising (1) silicon oxide and (2) boron oxide or a combination of boron oxide and aluminum oxide, iron oxide, titanium oxide, gallium oxide and mixtures thereof is prepared using a quaternary ammonium cation derived from 1-adamantamine, 3-quinuclidinol or 2-exo-aminonorbornane as structure directing agent. The molecular sieve can be used for gas separation or in catalysts to prepare methylamine or dimethylamine, to convert oxygenates (e.g., methanol) to light olefins, or for the reduction of oxides of nitrogen n a gas stream (e.g., automotive exhaust).
