Abstract: Preparation of a polyoxymethylene dimethyl ether (I) comprises feeding methylal and trioxane to a reactor and reacting in the presence of an acidic catalyst, where the quantity of water introduced into the reaction mixture by means of the methylal, trioxane and/or the catalyst is less than 1 wt.%, related to the reaction mixture. Preparation of a polyoxymethylene dimethyl ether (I) of formula (H 3CO(CH 2O) nCH 3) (where n is 2-10) comprises feeding methylal and trioxane to a reactor and reacting in the presence of an acidic catalyst, where the quantity of water introduced into the reaction mixture by means of the methylal, trioxane and/or the catalyst are less than 1 wt.%, related to the reaction mixture.

Abstract: In a process for drying microporous, fluid-containing particles, the heat required for increasing the temperature is supplied by convection by reducing the interfacial tension of the fluid, preferably to 0 to 1/10, in particular to 0 to 1/20, of the interfacial tension of the fluid at room temperature, by appropriately increasing the temperature at from close to the critical pressure to supercritical pressure of the fluid. Furthermore, microporous, three-dimensionally networked particles are prepared by a process in which the drying process is used. In addition, an apparatus is used for carrying out the drying process, the apparatus comprising a pressure container having an inner container and pressure-withstanding outer container and suitable measuring and control apparatuses and pump apparatuses and heat exchangers, the inner container being provided for holding the particles to be dried and a gap being provided between the inner container and the outer container.

Abstract: An aqueous solution of free hydroxylamine is prepared by treating a hydroxylammonium salt with ammonia by the countercurrent method in a stripping column by a process in which hydroxylamine is liberated and at the same time the solution obtained is separated by distillation into an aqueous hydroxylamine solution and a salt fraction. The novel process can be carried out in a simple and gentle manner and on a large scale. The danger of decomposition is minimized owing to the low thermal load, the low concentration of hydroxylamine and the short residence time in the process.
