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.
L'invention concerne un procédé permettant d'effectuer une réaction solide-liquide, selon lequel, a) une suspension de réaction est préparée, ladite suspension contenant un premier agent réactif en suspension et un second agent réactif en solution, dans un milieu de suspension, un des produits de réaction figurant sous forme non dissoute dans le milieu de suspension ; b) la suspension de réaction est guidée à travers une zone de réaction allongée, le nombre de Reynolds de l'écoulement étant inférieur à 2.000, et c) le produit de réaction non dissous obtenu est séparé. Ledit procédé présente l'avantage que le produit de réaction non soluble s'obtient sous forme aisée à filtrer.
