Industrial Applications of DITRIDECYL 3,3'-THIODIPROPIONATE
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Antioxidant for polyolefins such as polypropylene and polyethylene | Added during polymer melt processing to provide synergistic antioxidant protection by scavenging peroxy radicals and decomposing hydroperoxides |
| Rubber Industry | Heat stabilizer for synthetic rubbers (e.g., styrene-butadiene rubber, polybutadiene rubber) | Used in combination with primary antioxidants (e.g., hindered phenols) during the compounding stage to enhance long-term thermal aging resistance of vulcanized compounds |
| Lubricants | Secondary antioxidant for industrial lubricating oils and greases | Formulated with other antioxidants (e.g., alkylated diphenylamines) to inhibit oxidative degradation of base oils at elevated temperatures |
Manufacturing Quality Control of DITRIDECYL 3,3'-THIODIPROPIONATE
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of impurities under natural light or standard illumination. The product should typically appear as a colorless to pale yellow transparent liquid. |
| Acid Value | Titration Method (GB/T 601 or ASTM D974) | Using phenolphthalein as an indicator, titrate the free acid in the sample with standardized potassium hydroxide ethanol solution. Calculate the milligrams of KOH consumed per gram of sample (mg KOH/g). Used to assess residual acid content or degree of hydrolysis. |
| Hydroxyl Value | Acetylation-Titration Method (GB/T 7383 or ASTM D4274) | React hydroxyl groups in the sample with acetic anhydride to form esters, then back-titrate excess acetic anhydride with base. Calculate the hydroxyl value as mg KOH/g, used to evaluate by-product formation or unreacted raw material content. |
| Color | Platinum-Cobalt Colorimetric Method (GB/T 3143 or ASTM D1209) | Compare the sample with standard platinum-cobalt solutions to determine its Hazen (APHA) color units, reflecting product purity and thermal stability. |
| Purity / Main Component Content | Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) | Use GC (commonly with FID detector) or HPLC (e.g., C18 reversed-phase column with UV detector) for separation and quantification. Determine the content of dithiopropionic acid di(tridecyl ester) via peak area normalization or external standard method, typically requiring ≥98.0%. |
| Moisture Content | Karl Fischer Titration (GB/T 6283 or ASTM E1064) | Determine water content through quantitative reaction between Karl Fischer reagent and moisture in the sample using coulometric or volumetric methods. Typically requires ≤0.1% to prevent hydrolysis effects on product quality. |
| Ash Content | High-Temperature Incineration Method (GB/T 7385 or ASTM D482) | Incinerate the sample at high temperature (typically 750±25°C) in a muffle furnace until constant weight, then weigh the residual inorganic matter. Used to assess inorganic impurity levels (generally requires ≤0.05%). |
| Thermal Stability (Optional) | Differential Scanning Calorimetry (DSC) or Thermogravimetric Analysis (TGA) | Use DSC to measure melting or decomposition temperatures, or TGA to monitor mass loss during heating, to evaluate thermal stability during processing or storage. |
