| Polymer Industry | Synthetic Monomer | Serves as a comonomer or crosslinking agent in polymerization reactions to modify the properties of polyester or polyurethane materials. |
Manufacturing Quality Control of 4-Hydroxy-2-butanone
| 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 using a calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium; endpoint detected amperometrically. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator or potentiometric endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity against platinum-cobalt standard solutions or measurement of absorbance at 430 nm in a 10 cm cell. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known volume under controlled conditions followed by weighing of non-volatile residue after drying to constant mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal content after acid digestion and chelation, based on absorption of element-specific hollow cathode lamp radiation. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separation and conductivity detection of chloride ions in aqueous extract, or argentometric titration with silver nitrate and potentiometric endpoint. |
| Aldehyde Impurities (e.g., Acetaldehyde) | Gas Chromatography (GC) with FID or Headspace GC | Separation and quantification of volatile aldehydes using polar capillary column and flame ionization detection. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of specified sample mass to dryness followed by weighing of residue after heating at 105 degC to constant weight. |
| Odor | Sensory Evaluation (Qualified Panel) | Assessment by trained personnel against defined odor descriptors and intensity scale per established internal SOP for off-odor detection. |
