Industrial Applications of DEPS
| Industry | Application | Process |
|---|---|---|
| Cosmetics | Used as a surfactant in cleansing products | Produced via reaction of propargylamine with propane sultone to form a zwitterionic structure |
| Coatings | Used as a wetting and dispersing agent | Prepared via esterification of propargylamine with propane sultone |
| Cleaners | Used as a soil-removing agent and foam stabilizer | Generated via neutralization of propargylamine with propane sultone to yield a zwitterion |
Manufacturing Quality Control of DEPS
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample (e.g., colorless to pale yellow transparent liquid) under natural or standard lighting conditions. |
| pH Value | pH Meter Method | Dissolve the sample in deionized water and measure the pH using a calibrated pH meter. The typical range is 5.0–8.0. |
| Active Ingredient Content | Non-aqueous Titration or Two-phase Titration | Titrate the tertiary amine structure using perchloric acid in a non-aqueous medium; or use a toluene/water two-phase system with crystal violet as indicator. |
| Sodium Chloride (NaCl) Content | Silver Nitrate Titration or Ion Chromatography | Titration: Use K₂CrO₄ as indicator and titrate Cl⁻ with standard AgNO₃ solution. Ion chromatography offers higher precision and allows simultaneous determination of multiple ions. |
| Moisture Content | Karl Fischer Method | Use coulometric or volumetric Karl Fischer moisture analyzer to accurately determine trace water content in the sample. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine residual heavy metals such as lead, arsenic, mercury, and cadmium, ensuring compliance with pharmacopoeial or cosmetic raw material standards. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Detect solvent residues (e.g., ethanol, acetone) using a capillary column and quantify with an FID detector. |
| Structural Confirmation | Nuclear Magnetic Resonance (¹H-NMR, ¹³C-NMR) or FTIR | NMR confirms characteristic peaks in the molecular structure (e.g., -N⁺(CH₂CH₃)₂, -C≡C-H, -SO₃⁻); FTIR identifies functional groups. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measure weight loss under programmed temperature increase to evaluate thermal decomposition temperature and stability. |
| Surface Tension | Ring Method or Drop Volume Method | Use a tensiometer to measure the surface tension of aqueous solutions at specific concentrations to evaluate surfactant performance. |
