| titleOfInvention | Process for the preparation of ethers, esters or acid anhydrides |
| abstract | The present invention is an insoluble halide salt formed on a filter element and formed by flowing a cake of a first reactant selected from an organic acid or an oxygen-containing inorganic acid and an alcoholate by a solution of a second reactant selected from an inorganic acid or an organic acid halide and an alkyl halide. When it remains on a filter element, it is related with the method which can advantageously obtain an ether, an ester, or an acid anhydride. This method allows for easy separation of halide salts in a substantially quantitative manner.n n n Ether anhydrides, ester anhydrides, acid anhydrides, insoluble halide salts |
