Industrial Applications of (S)-(-)-Propylene Carbonate
| Industry | Application | Process |
|---|---|---|
| Lithium-ion batteries | Electrolyte additive | Mixed with ethylene carbonate, diethyl carbonate, and other components to enhance SEI film stability and low-temperature performance |
| Pharmaceuticals | Chiral resolving agent / asymmetric synthesis intermediate | Used in asymmetric epoxidation or ring-opening reactions for the production of chiral drugs such as β-blockers and antidepressants |
| Organic synthesis | Chiral solvent / catalyst ligand | Employed as a green chiral solvent in asymmetric catalytic reactions or coordinated with metal complexes to form chiral catalytic systems |
Manufacturing Quality Control of (S)-(-)-Propylene Carbonate
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color, transparency, and presence of suspended particles or precipitates under natural light or standard illumination. |
| Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Compare characteristic infrared absorption peaks with reference spectra to confirm the presence of functional groups in the molecular structure (e.g., carbonate C=O, C-O). |
| Specific Optical Rotation | Measure the specific optical rotation of the sample at a specified wavelength (typically sodium D line, 589 nm) and temperature to verify optical purity and (S)-configuration. | |
| Assay | Gas Chromatography (GC) | Use capillary column gas chromatography with area normalization or internal standard method to determine the content of the main component and evaluate product purity. |
| Optical Purity / Enantiomeric Excess (ee value) | Chiral Gas Chromatography (Chiral GC) | Separate enantiomers using a chiral stationary phase column; calculate the proportion of (S)-isomer from peak areas to determine enantiomeric excess (ee%). |
| Moisture Content | Karl Fischer Titration | Determine trace moisture content by potentiometric or coulometric titration to ensure compliance with drying requirements (typically ≤0.1%). |
| Boiling Point/Boiling Range | Distillation Method or GC Retention Time Comparison | Determine boiling range by atmospheric or vacuum distillation, or indirectly assess volatile impurities by comparing GC retention times with those of reference standards. |
| Refractive Index | Abbe Refractometer | Measure refractive index at a specified temperature as an auxiliary identification and purity indicator. |
| Density | Densitometer or Pycnometer Method | Determine density at standard temperature (e.g., 20°C) for quality consistency control. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detect organic solvents possibly remaining from manufacturing processes (e.g., acetone, toluene), ensuring compliance with ICH Q3C guideline limits. |
| Acid Value/Acidity | Acid-Base Titration | Titrate with standardized sodium hydroxide solution using phenolphthalein as indicator to determine free acid content (expressed as mg KOH/g). |
| Color | Platinum-Cobalt Colorimetric Method | Compare sample color with standard platinum-cobalt solutions to evaluate color intensity, indicating the presence of impurities or degradation products. |
