English name: Cyanuric fluoride CAS:675-14-9 EINECS: No. 211-620-8 MDL Number: MFCD00014597 Molecular weight:135.05 Appearance: colorless liquid. Boiling point: 69.5-70.5℃. Melting point: -38°C Boiling point: 73-74°C Density: 1,6 g/cm3 Refractive index: 1.348 Flashpoint: 73-74°C Solubility: soluble in chloroform, carbon tetrachloride, ether, dioxane, and miscible in ketones. Decomposes violently when exposed to water and alcohol. Acidity coefficient (pKa): -2.62±0.10 (Predicted) Sensitivity: Moisture sensitive BRN: 124237 Use 1: Mainly used to prepare reactive dyes Use two: used in organic synthesis. Overview: Cyanuric fluoride is a key intermediate in the synthesis of fluorinated s-triazine reactive dyes. Compared with traditional chlorotriazine reactive dyes, fluorinated s-triazine reactive dyes have the following five advantages: 1. Energy saving, low dyeing temperature (medium temperature type) 60℃, lower than KE type reactive dyes and equivalent to M type reactive dyes. 2. Emission reduction, environmental protection, and high color fixation rate. The color fixation rate is 15 to 20 percentage points higher than that of the corresponding chlorotriazine reactive dyes. It can not only improve the utilization rate of dyes but also reduce environmental pollution during the printing and dyeing process. 3. The dye has good stability. 4. High peroxide resistance and stability. 5. Not restricted by AOX regulations.
