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.
Claims12
A process for carrying out a liquid/solid reaction which comprises
- a) preparing a reaction suspension in which a first reactant selected from among salts of organic and oxygen-containing inorganic acids and alkoxides is present 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,
- b) passing the reaction suspension through an elongated reaction zone so that the Reynolds number of the stream is less than 20,000, wherein the longitudinal axis of the reaction zone is vertical and the reaction suspension is passed through the reaction zone opposite to the direction of gravity, and
- c) separating off the insoluble reaction product formed by filtration.
