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: Described is a process for the preparation of a particulate tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione product by combining a first aqueous solution comprising methylammonium N-methyldithiocarbamate with a second aqueous solution comprising formaldehyde, followed by separation and drying of the resulting solid, which comprises combining the first and the second aqueous solutions in such a way that the ratio between the concentrations of dithiocarbamate functions and of formaldehyde is essentially constant in the reaction mixture over time during the duration of the reaction.

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 whi ch is dissolved in the same, one of the reaction products being insoluble in th e 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 advantageo us in that the insoluble reaction product is obtained in a form which is easy t o filter.

Abstract: A method for the production of a particle-containing preparation of tetrahyd ro- 3,5-dimethyl-1,3,5-thiadiazin-2-thione, by combination of a first aqueous solution containing methylammonium-N-methyldithiocarbamate with a second solution containing formaldehyde and separation and drying of the solid form ed is disclosed. The invention is characterised in that the first and second solutions are combined such that over the duration of the reaction the ratio of the concentration of dithiocarbamate functions and formaldehyde in the reaction mixture remains essentially constant over time.
