    Abstract: A process for carrying out a liquid/solid reaction comprises a) preparing a reaction suspension in which a first reactant is present in suspended form and a second reactant is present in dissolved form in a suspension medium, where one of the reaction products is insoluble in the suspension medium, b) passing the reaction suspension through an elongated reaction zone so that the Reynolds number of the stream is less than 20,000 and c) separating off the insoluble reaction product formed. The process has the advantage that the insoluble reaction product is obtained in a readily filterable form.

    Abstract: The invention relates to a method for removing sulfur dioxide from a dry gas stream which comprises following steps: (a) adding a hydrogen-peroxide-comprising liquid to the gas stream, sulfuric acid forming from the hydrogen peroxide and the sulfur dioxide and (b) condensing, absorbing or aerosol precipitation of the sulfuric acid formed. The admixed hydrogen-peroxide-comprising liquid is mixed with the dry gas stream in the course of less than 0.3 s in such a manner that the admixed liquid is essentially homogeneously distributed in the gas stream. Furthermore, the invention relates to an apparatus for removing sulfur dioxide from a dry gas stream which comprises at least one atomizing nozzle for adding the hydrogen-peroxide-comprising liquid and a filter or aerosol separator, arranged downstream, in the direction of flow of the gas stream, of the at least one atomizing nozzle, in each case at least one atomizing nozzle being arranged on a cross sectional area of 300 to 350 cm 2 .

    Abstract: A process for preparing ethers, esters or acid anhydrides is disclosed, wherein a cake of a first reactant selected from salts of organic or oxygen-containing inorganic acids or alkoxides disposed on a filtering element is allowed to flow though by a solution consisting of a second reactant selected from inorganic or organic acid halides and alkyl halides, whereby the formed insoluble halide salt remains on the filtering element, which enables the halide salt to be easily separated in an essentially quantitative manner.

    Abstract: A process is described for preparing ammonium salts of aromatic carboxylic acids by reacting an aromatic carboxylic acid with ammonia in an aprotic solvent, which comprises carrying out the reaction in a closed vessel by continuously introducing a solution of the aromatic carboxylic acid in the aprotic solvent and passing in gaseous ammonia so that an ammonia partial pressure in the range from 0.1 to 3 bar is maintained in the gas space of the vessel, and discharging a suspension of the ammonium salt in the aprotic solvent. The process allows the preparation of ammonium salts of defined crystal size having a narrow size distribution.

    Abstract: A method for the production of ammonium salts of aromatic carboxylic acids b y reaction of an aromatic carboxylic acid with ammonia in an aprotic solvent i s disclosed. Said reaction is carried out in a closed vessel and a solution of the aromatic carboxylic acid in an aprotic solvent and gaseous ammonia are continuously introduced into the vessel, such that a partial pressure of ammonia of 0.1 to 3 bars is maintained in the gas chamber of the vessel and a suspension of the ammonium salt separates out in the aprotic solvent. The method permits the production of ammonium salts with defined crystal size an d a narrow size distribution.
