METHOD FOR PRODUCING ETHERS, ESTERS OR ACID ANHYDRIDES

摘要

Ethers, esters or acid anhydrides are advantageously obtained when a cake situated on a filtering element and consisting of a first reactant, which is selected among salts of organic or oxygen-containing inorganic acids or alcoholates, is flown though by a solution consisting of a second reactant, which is selected among inorganic or organic acid halides and alkyl halides, whereby the formed insoluble halide salt remains on the filtering element. This enables the halide salt to be easily separated in an essentially quantitative manner.
