Industrial Applications of DIETHYL ETHYLPHOSPHONATE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for organophosphorus insecticides | Used to synthesize organophosphorus pesticides such as dichlorvos and mevinphos via reactions with formaldehyde, dimethylamine, and other reagents |
| Pharmaceuticals | Intermediate for drug synthesis | Participates in the synthesis of anticholinergic agents and nerve agent antidotes (e.g., pralidoxime derivatives) through condensation, hydrolysis, and other reactions to construct the phosphonyl moiety |
| Materials Science | Flame retardant additive | Functions as a phosphorus-containing flame retardant component in polyurethane foams and epoxy resins, operating via combined gas-phase and condensed-phase flame inhibition mechanisms |
| Organic Synthesis | Raw material for phosphate ester synthesis | Under catalytic conditions, undergoes transesterification or substitution reactions with alcohols, phenols, or amines to produce functionalized phosphate esters |
Manufacturing Quality Control of DIETHYL ETHYLPHOSPHONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; separation based on volatility and polarity. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H3PO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison to APHA Scale | Compares sample color to platinum-cobalt standard solutions under controlled lighting and viewing conditions. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index at 20 C | Abbe Refractometer | Measures bending of light as it passes through sample at specified temperature to infer composition purity. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume at controlled temperature and weighs non-volatile residue after drying. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state metal atoms in flame or graphite furnace at characteristic wavelength. |
| Phosphate Esters (related impurities) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies structurally related ester impurities via retention time and mass spectral fragmentation. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporates sample to dryness and weighs residual solids after ashing at 550 C to remove organic volatiles. |
| Flash Point | Closed Cup Pensky-Martens Tester | Determines lowest temperature at which vapor forms ignitable mixture with air under standardized closed vessel conditions. |
