Process for heterogeneously catalyzed preparation of carboxylic acid derivatives using a reactor system comprising at least one reservoir vessel V, feed lines, at least one pump and a reaction vessel R, characterized in that a permanent gas flow through the reaction vessel R is applied through a gas feed line, and in which a reaction chamber in which the heterogeneous catalyst is not introduced in tightly packed form is delimited by at least two filters such that both the mass flow and the gas flow are passed through the reaction chamber.

Process for heterogeneously catalyzed preparation of carboxylic acid derivatives
