Cyanuric fluoride #CAS675-14-9
Cyanuric fluoride is a key intermediate in the synthesis of fluorine homotriazine reactive dyes. Compared with the traditional chlorotriazine reactive dyestuff, fluorine homotriazine reactive dyestuff has the following five advantages:
1. Energy saving, low dyeing temperature (medium temperature type) 60℃, lower than KE type reactive dyestuff and comparable to M type reactive dyestuff.
2. Emission reduction, environmental protection, high fixation rate, 15-20 percentage points higher than the corresponding chlorotriazine reactive dyestuff fixation rate, can improve the utilization rate of dyestuff, but also reduce the environmental pollution in the printing and dyeing process.
3. Good stability of dyestuff.
4. High stability of peroxide resistance.
5. Not restricted by AOX regulations.
Application of Cyanuric fluoride
Cyanuric fluoride acts as a fluorinating agent used in the conversion of carboxylic acids into acyl fluorides. It is used as a precursor for fibre-reactive dyes. It is a specific reagent for tyrosine residues in enzyme. Further, it is involved in the preparation of cyanuric acid by hydrolysis.
