Manufacturing Quality Control of 1,4-DICYANO-2-BUTENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample is ignited at 700–800 °C to volatilize organic matter; inorganic residue is weighed after cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Sample digested with nitric/hydrochloric acid; lead concentration measured by absorbance of ground-state atoms at 283.3 nm. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on anion-exchange column; quantified via conductivity response relative to calibration standards. |
| Acid Value | Potentiometric Titration with standardized NaOH | Neutralization of acidic impurities (e.g., residual HCl or carboxylic acids) using alcoholic KOH/NaOH; endpoint determined by pH inflection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample solution color intensity against platinum-cobalt standard scale, or absorbance measurement at specified wavelength. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Residual Solvents (e.g., acetone, methanol) | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvents partitioned into headspace above heated sample; quantified via GC-FID peak area against internal standard calibration. |
| Specific Optical Rotation | Polarimetry | Measurement of angular rotation of plane-polarized light caused by chiral impurities or enantiomeric excess in solution at specified wavelength and temperature. |
| Appearance (Clarity & Color) | Visual Inspection in Nessler Tube | Assessment of liquid clarity (free from suspended particles) and color against water-white standard under controlled lighting. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determination of mass per unit volume based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index | Abbe Refractometer | Measurement of light bending angle at air-sample interface; correlates with molecular composition and purity at specified temperature and wavelength (589 nm). |
