Industrial Applications of Phosphoric acid 1-methylvinyldiethyl ester
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for organophosphorus insecticides | Phosphate ester precursor used in the synthesis of insecticides such as chlorpyrifos and methyl chlorpyrifos; prepared via substitution reaction with 2-chloropyridine or related heterocyclic compounds |
| Pharmaceuticals | Intermediate for drug synthesis | Phosphorylating agent or protecting group reagent employed in constructing phosphate ester side chains of nucleoside-based drugs (e.g., antiviral prodrugs); typically reacts with alcohols or phenols under anhydrous conditions via transesterification or alkylation |
| Materials Science | Flame retardant additive | Phosphorus-containing flame retardant synergist incorporated into thermoplastic and thermosetting polymers (e.g., epoxy resins, polycarbonates); promotes char formation and suppresses free-radical chain reactions by releasing phosphate derivatives at elevated temperatures |
Manufacturing Quality Control of Phosphoric acid 1-methylvinyldiethyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine and sulfur dioxide to stoichiometrically react with water in the sample. |
| Acidity (as H3PO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or phenolphthalein endpoint detection. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 455 nm. |
| Density | Digital Density Meter | Measurement of mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated refractometer at controlled temperature. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using ion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using flame or graphite furnace AAS with lead-specific hollow cathode lamp. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature incineration of sample in platinum crucible. |
| Phosphoric Acid Esters (Related Substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantitative assessment of structurally related ester impurities via retention time and mass spectral matching. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Measurement of weight loss upon controlled heating to assess non-volatile residue and thermal stability profile. |
| pH of Aqueous Solution (10% w/w) | pH Meter Measurement | Direct potentiometric measurement of hydrogen ion activity in aqueous dispersion using calibrated pH electrode. |
