Abstract: A process for preparing vicinal diols or polyols from an organic reaction mixture containing formic esters of vicinal diols or polyols, in which water is added to the reaction mixture, without addition of bases, and the formic esters are hydrolyzed in a subsequent thermal treatment, the aqueous formic acid is removed, and vicinal diols or polyols remain behind.

Abstract: The invention relates to a method for the production of 1-(2-sulphoethyl)-pyridinium betaine, whereby pyridine is reacted with a sulphoethylating reagent from a group comprising carbyl sulphate, ethionic acid or the salt thereof and vinyl sulphonic acid or vinyl sulphonate, and the reaction occurs in an aqueous solution or in pyridine.

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 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: 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.
