Industrial Applications of Diisononyl phthalate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Primary plasticizer for polyvinyl chloride (PVC), used in flexible PVC products such as cable compounds, synthetic leather, and floor coverings | Blended with PVC resin and processed via extrusion, calendering, or injection molding |
| Coatings and Inks | Plasticizing and flow-enhancing additive for solvent-based coatings and printing inks | Added during grinding/dispersion to improve pigment wetting and film flexibility |
| Sealants and Adhesives | Plasticizing component in silicone and acrylic sealants, enhancing low-temperature elasticity and bond durability | Incorporated as a liquid additive and uniformly mixed with other components during compounding or stirring |
Manufacturing Quality Control of Diisononyl phthalate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Determination of Di-C8-10 branched alkyl phthalate (C9 enriched) content | Gas Chromatography-Mass Spectrometry (GC-MS) | Samples are extracted with a suitable solvent (e.g., n-hexane or toluene), cleaned up using a silica gel column or solid-phase extraction (SPE) to remove interferences, and derivatized if necessary. The extract is then injected into a GC-MS system. Components are separated on a capillary chromatographic column and detected by a mass spectrometer for qualitative and quantitative analysis. Target compounds are accurately identified and quantified by comparing retention times and mass spectra with those of reference standards. This method is suitable for detecting low concentrations of target analytes in complex matrices. |
| High-Performance Liquid Chromatography with UV/Diode Array Detection (HPLC-UV/DAD) | Samples are extracted with organic solvents (e.g., methanol or acetonitrile) and filtered prior to direct injection. A reversed-phase C18 column is used with gradient elution (acetonitrile-water or methanol-water). Detection is performed using a UV detector within the wavelength range of 220–280 nm. This method is suitable for thermally unstable or non-volatile compounds, requires no derivatization, and is simple to operate, though sensitivity is slightly lower than GC-MS. | |
| Gas Chromatography with Flame Ionization Detection (GC-FID) | After solvent extraction and cleanup, the sample is injected into a gas chromatograph. Separation is achieved using a non-polar or mid-polarity capillary column, and the target analytes are detected by a flame ionization detector (FID). Quantification is performed using external or internal standard methods. This method is cost-effective and stable, suitable for routine analysis of samples with high analyte concentrations, but lacks the confirmatory capability of mass spectrometry. | |
| Impurity and Degradation Product Analysis | GC-MS or LC-MS/MS | High-resolution or tandem mass spectrometry techniques are used to qualitatively analyze trace impurities or potential hydrolysis/oxidation degradation products beyond the main component. By matching with standard spectral libraries and analyzing fragment ions, potentially harmful by-products can be identified, ensuring product purity and safety. |
| Screening of Volatile and Semi-Volatile Organic Compounds | Thermal Desorption-Gas Chromatography-Mass Spectrometry (TD-GC-MS) | Solid or highly viscous samples are subjected to thermal desorption, directly releasing volatile components into the GC-MS system. This method detects residual solvents or low molecular weight degradation products, and is applicable for process control during manufacturing and safety evaluation of final products. |
