Industrial Applications of TRIMETHYLENE BORATE
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | As a methylating agent | Involved in transesterification or nucleophilic substitution reactions |
| Pharmaceutical Intermediates | Synthesis of boron-containing drugs or radiolabeled compounds | Used in precursors for boron neutron capture therapy (BNCT) |
| Materials Science | Preparation of organic boron-based functional materials | Sol-gel process or polymerization |
| Analytical Chemistry | Boron standard reference material or derivatization reagent | Applied in sample preparation prior to chromatographic or mass spectrometric analysis |
Manufacturing Quality Control of TRIMETHYLENE BORATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Boric Acid Triethyl Ester Content) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acidity (as H3BO3) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color | Visual Comparison Against APHA Scale | Compares sample color to platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Pycnometry or Digital Density Meter | Measures mass per unit volume using calibrated glass pycnometer or oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using Abbe refractometer at specified temperature. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Atomizes and excites sample in plasma; detects elemental emission lines for multi-element quantification. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporates known volume to dryness and weighs residual solids after drying at 105 C. |
| Boiling Range | Distillation with Thermometer and Graduated Receiver | Determines temperature interval over which 90% of sample distills under controlled atmospheric pressure. |
| Appearance (Clarity) | Visual Inspection in Glass Cell | Assesses transparency and absence of suspended particles or phase separation in clear container under white light. |
