Abstract: Gas-phase esterifications of six kinds of carboxylic acid with ethyl alcohol catalyzed by nio-bic acid at normal pressure were studied.The results show that the conversion of ethanol is very high in each esterification here, it is up to 92% for esterification of acetic acid with ethanol, and that, especially, the selectivities for all the esterification are up to 100%.

Key words: Catalyst of niobic acid, Esterif ication, Catalysis
