Method for producing sodium dichloroisocyanurate by replacing caustic soda with soda ash
Thread Content
Previously, our company used caustic soda to produce sodium dichloroisocyanurate; now we use soda ash instead of caustic soda for this production. There are issues such as high product viscosity and difficulty in suction filtration. I wonder if any colleagues have experience in this area; please share your insights. Thank you.
Excuse me, has your company's production problem been solved?
When using soda ash instead of caustic soda to produce sodium dichloroisocyanurate, it is necessary to readjust the proportions of all raw materials. The amount of soda ash required should be calculated based on cyanuric acid as a reference. Since soda ash contains virtually no moisture, the amount of water originally present in the caustic soda must be determined and added to the process water. Otherwise, this will result in smaller crystals of sodium dichloroisocyanurate and a more viscous slurry (which may sometimes become porridge-like), making separation in subsequent processing steps difficult. Additionally, after changing the raw materials, the process conditions should also be adjusted accordingly.
