Abstract
Ethers, esters or acid anhydrides are advantageously obtained when a cake of a first reactant selected from salts of organic or oxygen-containing inorganic acids or alkoxides disposed on a filter element is flowed through by a solution of a second reactant selected from inorganic or organic acid halides and alkyl halides, so that the insoluble halide salt formed remains on the filter element. The halide salt can thus be removed substantially quantitatively in a simple manner.
