Industrial Applications of Dilauryl thiodipropionate
| Industry | Application | Process |
|---|---|---|
| Plastics Processing | Secondary antioxidant for polyolefins (e.g., polypropylene, polyethylene) | Used in combination with primary antioxidants (e.g., phenolic antioxidants) during polymerization or pelletization |
| Plastics Processing | Stabilizer for polyvinyl chloride (PVC), ABS resins, and other polymers | Incorporated via melt compounding or direct addition to the resin system to provide long-term thermal stability |
| Lubricants Industry | Antioxidant for lubricating oils and greases | Added to base oils to inhibit oxidative degradation at elevated temperatures |
| Rubber Industry | Antidegradant for synthetic rubber | Added during rubber compounding or vulcanization to prevent aging |
| Food Packaging | Additive for food-contact materials (e.g., polypropylene cling film) | Added within regulatory limits to prevent oxidative degradation of the material and ensure food safety |
Manufacturing Quality Control of Dilauryl thiodipropionate
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Place an appropriate amount of sample in a clean, dry glass container and visually examine its color and state under natural light. It should appear as a white to slightly yellow waxy solid without visible impurities. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a melting point apparatus or capillary method. The typical melting point range for DLTDP is 38–42°C. Used to assess purity and material consistency. |
| Content (Active Ingredient) | Gas Chromatography (GC) | Use a gas chromatograph equipped with an FID detector and an appropriate polarity capillary column (e.g., DB-5). Determine the content of DLTDP using external standard or normalization methods. Typically required to be ≥97%. |
| Acid Value | Acid-Base Titration | Dissolve the sample in an ethanol-toluene mixture and titrate with standardized potassium hydroxide ethanol solution. Calculate the milligrams of KOH consumed per gram of sample (mg KOH/g). Reflects free acid content; typically required ≤0.5 mg KOH/g. |
| Color | Platinum-Cobalt Colorimetry (APHA) | Dissolve the sample in an appropriate solvent (e.g., toluene), then use a spectrophotometer or colorimeter to measure absorbance at specific wavelengths and convert it into platinum-cobalt units (Pt-Co). Evaluates product color; generally required ≤100 APHA. |
| Moisture | Karl Fischer Method | Use a coulometric or volumetric Karl Fischer moisture analyzer to accurately determine the moisture content of the sample. Typically required ≤0.1% (w/w). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion with nitric acid-hydrogen peroxide, use atomic absorption spectroscopy or inductively coupled plasma mass spectrometry to determine residual heavy metals such as lead, arsenic, mercury, and cadmium. Must comply with pharmacopoeia or food additive standards (e.g., lead ≤5 ppm). |
| Residue on Ignition | Ignition Residue Method | Incinerate the sample in a high-temperature muffle furnace (approximately 800±25°C) until constant weight is achieved, and calculate the percentage of remaining inorganic matter. Reflects inorganic impurity content; generally required ≤0.1%. |
| Relative Density | Density Bottle Method | Use a density bottle of known volume to measure the sample's mass at a specified temperature (e.g., 20°C) and calculate the density. Used as an auxiliary identification parameter. |
| Oxidation Induction Time (OIT) | Differential Scanning Calorimetry (DSC) | Conduct DSC testing under oxygen atmosphere at a defined heating rate to determine the time or temperature at which significant oxidative exothermic reaction begins. Assesses antioxidant stability and performance. |
