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, and separating the solid form the resulting suspension.

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.
