This multi-stage synthesis is critical to ensure the high purity, consistent quality, and optimal performance of the final product. The primary raw material for this compound is cyanuric acid, which undergoes a carefully managed chlorination process, followed by neutralization and crystallization, to yield the desired dihydrate form.
High-purity cyanuric acid, obtained from urea synthesis, is carefully dissolved in an aqueous medium to form a controlled slurry, serving as the foundational raw material for the subsequent reactions.
Gaseous chlorine is precisely bubbled through the prepared cyanuric acid solution. This crucial chlorination step is performed under stringent conditions of temperature and pH, facilitating the substitution of hydrogen atoms on the cyanuric acid ring with chlorine, leading to the formation of dichloroisocyanuric acid intermediates.
A controlled amount of sodium hydroxide or sodium carbonate is introduced to neutralize the dichloroisocyanuric acid. This neutralization step promotes the formation of dichloroisocyanurate de sodium, which then selectively crystallizes out of the solution in its stable dihydrate form.
The crystallized sodium dichloroisocyanurate dihydrate is efficiently separated from the remaining mother liquor using advanced techniques such as centrifugation or filtration. The resulting wet cake then undergoes a meticulous drying process, achieving the precise moisture content and desired physical form (e.g., fine powder, uniform granular, or compressed tablets).
The finished product batches undergo rigorous quality control tests. These tests, conducted according to international standards such as ISO and ANSI, verify critical parameters like available chlorine content, moisture level, pH, and particle size distribution. Only products meeting these strict specifications are approved for packaging in moisture-proof, secure container111s.
The deployment of advanced manufacturing processes, including precise temperature control, continuous pH monitoring, and optimized reaction kinetics, is absolutely critical for maximizing product yield and achieving exceptional purity. Modern facilities utilize sophisticated technologies such as automated dosing systems and real-time analytical feedback to ensure consistent product quality across all batches, effectively minimizing the presence of impurities.
