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 preparing polyether polyols includes a precipitation step, a recrystallization step, and a reaction step. In the precipitation step, a multimetal cyanide compound is precipitated by reaction of a metal salt with a cyanometalate compound. In the recrystallization step, the multimetal cyanide compound precipitated above is recrystallized by adding further metal salt and/or further cyanometalate compound. The recrystallization forms a multimetal cyanide catalyst compound. In the reaction step, an initiator and one or more alkylene oxide are reacted in the presence of the multimetal cyanide catalyst compound.

Abstract: The invention relates to a process for preparing polyether alcohols by addition of alkylene oxides onto H-functional starter substances using multimetal cyanide compounds as catalysts, wherein the multimetal cyanide compound is prepared by a process comprising the steps: a) adding a metal salt solution to a cyanometalate solution at a specific stirring power epsilon in the range from 0.05 to 10 W/l, preferably from 0.4 to 4 W/l, a temperature in the range from 0° C. to 100° C., preferably from 20° C. to 60° C., and an addition time of from 5 to 120 minutes, b) reducing the specific stirring power epsilon to a value in the range from 0.03 to 0.8 W/l and at the same time adding a surface-active agent, c) heating the solution while stirring at a specific stirring power epsilon of from 0.03 to 0.8 W/l, to a temperature of not more than 100° C., preferably in the range from 55° C. to 75° C., d) adding further metal salt solution while stirring at a specific stirring power epsilon of from 0.03 to 0.8 W/l, e) when the conductivity begins to drop, dispersing the solid, for example by stirring while increasing the specific stirring power epsilon to >0.7 W/l or by installation of a pumped circuit with an appropriate pump or by means of a high-speed stirrer, f) stirring at the specific stirring power epsilon of step e) until the conductivity or the pH remains constant, g) separating off the multimetal cyanide compound and washing it with water and, if desired, h) drying the catalyst.

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.
