Embodiment 1
[0030] A, the caustic soda solution of 30% (wt %) of the cyanuric acid of 5Kg and 11Kg is dropped in the reactor, after stirring and reacting 30min, B, the chlorine that produces in the production of passing into metal lithium in the solution carries out chlorination reaction, controls chlorine The reaction temperature is 10°C. When the pH of the solution reaches 4, the reaction is stopped, and 8.0Kg of dichloroisocyanuric acid solid and 8Kg of mother liquor are obtained through centrifugation. C. Add 8Kg of pure water to the obtained dichloroisocyanuric acid solid , repeatedly stirred and washed 5 times, and centrifuged to obtain relatively pure dichloroisocyanuric acid solid, and the lotion was returned to step A for recycling. D, add 8Kg of pure water to the purer dichloroisocyanuric acid solid, add dropwise 30% (wt%) NaOH of 5.2Kg, stir and react for 60min, evaporate, cool and crystallize, and dry at 50°C for 1 hour to obtain Sodium dichloroisocyanurate products, after ana...
Embodiment 2
[0032] A, the caustic soda solution of 15% (wt %) of the cyanuric acid of 15Kg and 63Kg is dropped in the reactor, after stirring reaction 60min, B, the chlorine gas that produces in the production of passing into metal lithium in the solution carries out chlorination reaction, controls chlorine The reaction temperature is 35°C. When the pH of the solution reaches 6, the reaction is stopped, and 24.0Kg of dichloroisocyanuric acid solid and 54Kg of mother liquor are obtained through centrifugation. C. Add 72Kg of pure water to the obtained dichloroisocyanuric acid solid , repeatedly stirred and washed twice, centrifuged to obtain relatively pure solid dichloroisocyanuric acid, and the washing solution was returned to step A for recycling. D. Add 72Kg of pure water to the purer dichloroisocyanuric acid solid, add dropwise 15% (wt%) NaOH of 33Kg, stir for 30min, evaporate, cool and crystallize, and dry at 120°C for 30min to obtain dichloroisocyanuric acid The sodium isocyanurate ...
Embodiment 3
[0034] A, the caustic soda solution of 20% (wt %) of the cyanuric acid of 10Kg and 31Kg is dropped in the reactor, after stirring reaction 45min, B, the chlorine that produces in the production of passing into metal lithium in the solution carries out chlorination reaction, controls chlorine The chemical reaction temperature is 23 DEG C, when the pH of the solution reaches 7, stop the reaction, obtain 16Kg dichloroisocyanuric acid solid and 25Kg mother liquor through centrifugal separation, C, add 32Kg pure water in the dichloroisocyanuric acid solid that obtains, Stir and wash repeatedly 3 times, centrifuge to obtain relatively pure solid dichloroisocyanuric acid, and return the lotion to step A for recycling. D. Add 32Kg of sodium dichloroisocyanurate mother liquor to the purer dichloroisocyanuric acid solid, add dropwise 15.5Kg of 20% (wt%) NaOH, stir and react for 45min, evaporate, cool and crystallize, and dry at 85°C After 45 minutes, the sodium dichloroisocyanurate prod...
