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: 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: Preparation of a solid dosage form containing creatine (I) involves: (a) forming a mixture containing at least one water-soluble or water-swellable thermoplastic binder (II), (I) and 1-20 moles of water per mole of (I); (b) heating the mixture to or above the softening point of (II); and (c) shaping the plasticized mixture into the dosage form and cooling. Independent claims are included for the following: (i) the dosage forms obtained by the above process; and (ii) dosage forms containing (I) at 3.3 mmol or more per g of the dosage form, in finely dispersed or molecular dispersion form in a matrix of (II).

Abstract: A method for the production of ammonium salts of aromatic carboxylic acids by reaction of an aromatic carboxylic acid with ammonia in an aprotic solvent is 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 and a narrow size distribution.

Abstract: The invention relates to a method for carrying out a solid-liquid reaction, according to which a) a reaction suspension is prepared, containing a first reactant which is suspended in a suspension medium and a second reactant whi ch is dissolved in the same, one of the reaction products being insoluble in th e suspension medium, b) the reaction suspension is guided through a longish reaction zone, the Reynolds number of the flow being less than 20,000, and c ) the insoluble reaction product formed is separated. The method is advantageo us in that the insoluble reaction product is obtained in a form which is easy t o filter.
