Manufacturing Quality Control of 1,2-DICHLOROBUTANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (1,2-Dichlorobutane Content) | Gas Chromatography (GC) with FID detector | Separation and quantification based on retention time and peak area using a calibrated standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity against platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Measurement of mass per unit volume via resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporation of a known sample volume to dryness followed by weighing of residual solids. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion by measuring absorption of element-specific hollow cathode lamp radiation. |
| Residual Chlorine (Total Organic Chlorine) | Combustion Ion Chromatography (CIC) | High-temperature combustion converts organochlorines to chloride ions, detected by conductivity after ion chromatography separation. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides, followed by titration of liberated iodine with standardized sodium thiosulfate. |
| Boiling Range | Distillation (ASTM D86 or D1078) | Measurement of initial and final boiling points under controlled atmospheric pressure using standardized distillation apparatus. |
| Appearance (Clarity and Color) | Visual Inspection in Nessler Tube | Subjective assessment of clarity (absence of haze or suspended particles) and color against water-white reference under controlled lighting. |
