Industrial Applications of DIETHYL AZELATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Synthesis of pharmaceutical intermediates | Prepared via reaction of azelaic acid with ethanol |
| Coatings | Enhancement of coating performance | Added to coatings to improve physical properties and weather resistance |
| Plastics | Enhancement of plastic performance | Used as a plasticizer to improve flexibility and processability |
Manufacturing Quality Control of DIETHYL AZELATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; separation based on volatility and polarity. |
| Acid Value | Acid-Base Titration with KOH ethanol solution | Measures free carboxylic acid content by titration with standardized alkali to phenolphthalein endpoint. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically determines water via iodine generation proportional to water in sample. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color intensity to platinum-cobalt standard scale using standardized light path. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume from resonant frequency shift of vibrating U-tube filled with sample. |
| Refractive Index at 20 degC | Digital Refractometer | Measures ratio of light velocity in air vs. sample using critical angle of total internal reflection. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Weighs non-volatile inorganic residue remaining after combustion at 750 degC. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies trace metal elements by measuring characteristic atomic emission intensities after plasma atomization. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration monitored by silver ion-selective electrode potential change. |
| Ester Content (by saponification value) | Saponification Titration with KOH ethanol solution | Measures total ester groups by alkaline hydrolysis followed by back-titration of excess alkali. |
| Non-Volatile Residue | Gravimetric Evaporation at 105 degC | Determines residue weight after evaporating specified sample mass under controlled temperature and airflow. |
| Odor | Sensory Evaluation (Qualified Panel) | Assesses off-odor presence and intensity against reference standards using trained human assessors. |
