Industrial Applications of Bis(2-ethylhexyl) maleate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Plasticizer for polyvinyl chloride (PVC) | Used as a primary or secondary plasticizer; blended with PVC resin and processed via melt extrusion or calendering to improve flexibility, low-temperature performance, and processing flowability |
| Coatings Industry | Acrylic resin modification monomer | Participates in free-radical copolymerization to introduce flexible segments, thereby lowering the minimum film-forming temperature (MFT) and enhancing film toughness and adhesion |
| Adhesives Industry | Tackifier and modifier for pressure-sensitive adhesives | Copolymerized with acrylic ester monomers to adjust the copolymer’s glass transition temperature (Tg) and cohesive strength, improving initial tack and holding power |
| Inks Industry | Reactive diluent for UV-curable inks | Functions as a low-viscosity, highly reactive difunctional acrylate; undergoes crosslinking polymerization under UV irradiation to increase cure speed and film flexibility |
Manufacturing Quality Control of Bis(2-ethylhexyl) maleate
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Content Determination | Gas Chromatography (GC) | Using a gas chromatograph equipped with an FID detector, the content of DEHP in the sample is quantified by comparing it with a standard reference. The sample is extracted with an organic solvent and then injected for analysis, offering high sensitivity and good reproducibility. |
| HPLC | Utilizing a C18 reverse-phase chromatography column, with methanol-water as the mobile phase, and a UV detector (around 224 nm), this method is suitable for thermally unstable samples or substances that cannot be vaporized. | |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combining the separation capability of GC with the qualitative power of MS, this method can accurately identify and quantify organic impurities in DEHP (such as other phthalates and degradation products). |
| Residual Solvent Detection | Headspace-Gas Chromatography (HS-GC) | The sample is placed in a sealed headspace vial and heated, allowing volatile solvents to enter the gas phase. These are then detected using GC-FID, enabling the detection of residual solvents (such as methanol, acetone, dichloromethane, etc.) in accordance with pharmacopoeia requirements. |
| Migration Testing (Simulant Test) | GC or GC-MS | The sample is contacted with food simulants (such as ethanol or acetic acid solution) under specified temperature and time conditions, and the amount of DEHP migrating into the simulant is measured to assess safety. |
| Purity Analysis | Nuclear Magnetic Resonance Spectroscopy (NMR) | Using ¹H-NMR or ¹³C-NMR to confirm the compound structure and assess purity through peak area integration, this method is commonly used for standard reference verification. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measuring the mass change of the sample under programmed heating conditions to evaluate the decomposition temperature and thermal stability of DEHP during heating. |
| Infrared Spectroscopy Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Confirming molecular functional groups (such as ester group C=O stretching vibration around 1720 cm⁻¹) by comparing infrared absorption spectra with standard spectra, used for qualitative identification. |
