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 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 for carrying out a liquid/solid reaction comprises preparing a reaction suspension in which the first reactant is selected from salt of organic and oxygen-containing inorganic acids in suspended form and a second reactant selected from among inorganic and organic acid halides and alkyl halides is present in dissolved form in a suspension medium where one of the reaction products is insoluble in the suspension medium, then passing the reaction suspension through an elongated reaction zone so that the Reynolds number of the stream is less than 20,000 and then separating off the insoluble reaction product formed.

Abstract: A process for the production of ethers, esters or acid anhydrides comprises flowing a solution of an inorganic or organic acid halide and alkyl halide through a filter cake containing salts of organic or oxygen containing inorganic acids or alcoholates such that the insoluble halide salt formed remains of the filter.

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 which is dissolved in the same, one of the reaction products being insoluble in the 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 advantageous in that the insoluble reaction product is obtained in a form which is easy to filter.

Abstract: A solid pigment preparation contains by wt. (a) a pigment (60-95%); (b) a water-soluble anionic surfactant (5-40%) which is a polymer of an ethylenically unsaturated mono- and/or di-carboxylic acid optionally copolymerized with an acid function-free vinyl monomer, the alkoxylation product of such a (co)polymer or a salt of the (co)polymer or its alkoxylation product; and (c) a polyether-based nonionic surfactant (0-20%). An Independent claim is also included for production of the pigment preparation by wet comminuting pigment (A) in a suspension containing at least a part of (B) and optionally also component (C) and then optionally adding any remainder of (B) and/or (C) and drying the mixture.
