摘要

"Heteropoliu00e1cido catalyst for the production of lower aliphatic acid ester carboxu00eclico".Catalyst for use in the production of lower aliphatic carboxylic acid ester.Which is used in the production of carboxylic acid ester by esterification of a lower aliphatic carboxylic acid with a lower alcohol, lower in a gas phase and which can display alTA initial activity and is capable of stably and continuously carry out the reaction. The catalyst comprises an inorganic support and supported him for at least a heteropoliu00e1cido and / or its salt.
