Manufacturing Quality Control of 1,4-Dichloro-2-butyne
| 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 non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acidity (as HCl) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities (e.g., residual HCl) using standardized sodium hydroxide solution. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled conditions followed by weighing of non-volatile residue. |
| Color | Visual Comparison to APHA Scale | Comparison of sample color in a Nessler tube against platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via oscillation frequency of a U-shaped glass tube filled with the sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index based on critical angle measurement of light passing through the sample. |
| Chloride Ion (inorganic) | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an anion-exchange column followed by quantitative detection via electrical conductivity. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample decomposition by acid digestion, followed by quantification of total heavy metals using flame or graphite furnace AAS. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of specified sample volume to dryness at 105 degC, then weighing of residual solids. |
| Distillation Range | Capillary Gas Chromatography or ASTM D1078 | Measurement of initial and final boiling points using calibrated distillation apparatus or GC retention time correlation. |
| Organic Impurities (related substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and semi-quantification of impurities based on mass spectral libraries and relative response factors. |
