Industrial Applications of DIMETHYL PIMELATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a raw material or intermediate in the synthesis of non-steroidal anti-inflammatory drugs (e.g., ibuprofen) | Organic synthesis |
| Polymer materials | Used to produce polyester polyols for subsequent polyurethane resin synthesis | Condensation polymerization |
| Polymer materials | Used in the synthesis of polyesters (e.g., polyheptanedioates) for biodegradable materials | Condensation polymerization |
| Organic synthesis | Used to synthesize C7 diacid esters for functional group introduction | Esterification |
| Fragrance and flavor | Rarely used as a modifier in specialty fruit or creamy flavor formulations | Blending/mixing |
Manufacturing Quality Control of DIMETHYL PIMELATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry (APHA scale) | Measurement of yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Measurement of light bending angle at air-sample interface using a calibrated Abbe refractometer or digital instrument. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue remaining after controlled high-temperature ashing in a muffle furnace. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals via atomic emission spectroscopy after acid digestion and plasma excitation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of a known sample mass to dryness followed by weighing of residual solids after drying at 105 C. |
| Flash Point | Cleveland Open Cup (COC) | Determination of lowest temperature at which vapors ignite momentarily when exposed to a flame under standardized conditions. |
| Appearance | Visual Inspection | Assessment of liquid clarity and absence of suspended particles or phase separation against a white background under controlled lighting. |
