Industrial Applications of Dioctyl adipate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Used as a plasticizer for polyvinyl chloride (PVC) to enhance flexibility and low-temperature performance | Blended with PVC resin and processed via thermoplastic methods (e.g., extrusion, calendering, injection molding) |
| Rubber Industry | Used as a rubber plasticizer to improve elasticity and low-temperature properties | Mixed with natural or synthetic rubber in a compounding process, followed by vulcanization |
| Coatings Industry | Used as a plasticizer and flow agent in solvent-based coatings to improve film adhesion and flexibility | Dissolved in organic solvents and blended with resins and pigments prior to spray or roll coating |
| Fibers Industry | Used to plasticize cellulose acetate and cellulose nitrate, improving film-forming properties | Dissolved with cellulose esters in solvents, followed by spinning or film casting |
| Medical Devices | Used in the manufacture of flexible PVC medical tubing, blood bags, etc., meeting biocompatibility requirements | Processed using medical-grade raw materials and sterilized via high-temperature sterilization |
Manufacturing Quality Control of Dioctyl adipate
| Test Item | Common Test Methods | Method Summary |
|---|---|---|
| Purity | Gas Chromatography (GC) | Separation using a capillary column and quantitative analysis of the main component using an FID detector to evaluate product purity. |
| Moisture | Karl Fischer Titration | Utilizes the quantitative reaction of iodine with water; the trace moisture content in the sample is determined by potentiometric or visual endpoint detection. |
| Acid Value | Acid-Base Titration | Using phenolphthalein as an indicator, free acids are titrated with a standard potassium hydroxide ethanol solution to calculate the acid value (mg KOH/g). |
| Color | Platinum-Cobalt Colorimetry / Visual Color Comparison | Sample is compared with standard platinum-cobalt solutions to assess color depth, reflecting impurity or oxidation levels. |
| Density | Density Meter Method / Pycnometer Method | Density is measured at a specified temperature (e.g., 20 °C) for product identification and quality consistency control. |
| Refractive Index | Abbe Refractometer Method | The refractive index of the sample is measured at a specific temperature to assist in determining purity and batch consistency. |
| Flash Point | Cleveland Open Cup (COC) Method | The lowest temperature at which the vapor of the sample ignites upon exposure to a flame is measured to assess safe storage and transportation conditions. |
| Volatile Matter | Gravimetric Method (Oven Drying) | The sample is heated at a specified temperature and time, and weight loss is measured to evaluate the content of volatile impurities. |
| Appearance | Visual Inspection | Observe whether the sample is clear, transparent, and free of suspended particles or precipitates to preliminarily assess physical condition compliance. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion, residues of heavy metals such as lead, cadmium, mercury, and arsenic are measured to ensure compliance with environmental and safety standards. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Analyzes potentially residual organic solvents (e.g., toluene, n-hexane) through headspace sampling to control toxicity risks. |
