METHOD FOR THE PRODUCTION OF A PARTICLE-CONTAINING PREPARATION OF TETRAHYDRO- 3,5-DIMETHYL-1,3,5-THIADIAZIN-2-THIONE |
摘要 |
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. |
