Industrial Applications of Dinonyl phthalate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Plasticizer | Added to plastic substrates to enhance flexibility, processability, and service temperature range. |
| Coatings and Inks | Plasticizer | Incorporated into coating or ink formulations to improve flow and film formation, while enhancing durability and gloss of the final product. |
| Adhesive Manufacturing | Plasticizer | Used to adjust viscosity and cure characteristics of adhesives to meet specific application requirements. |
| Wire and Cable | Insulation Plasticization | Integrated into wire and cable insulation layers to increase material softness while maintaining good electrical properties. |
| Artificial Leather | Softening Agent | Added during artificial leather production to impart improved hand feel and abrasion resistance. |
Manufacturing Quality Control of Dinonyl phthalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DINP content) | GC-FID | Quantitative analysis using gas chromatography with flame ionization detection based on peak area comparison against certified reference standard. |
| Acid Value | Acid-Base Titration | Determination of free acid content by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Assessment of sample yellowness by matching against APHA color scale standards under controlled lighting conditions. |
| Density at 20 C | Pycnometry or Digital Density Meter | Measurement of mass per unit volume using calibrated pycnometer or oscillating U-tube density meter. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle in sample at specified temperature using Abbe refractometer. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric quantification of water via iodine generation and stoichiometric reaction with sample. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of known sample mass at 105 C followed by weighing of residual solids. |
| Flash Point (COC) | Cleveland Open Cup Method | Determination of lowest temperature at which vapors ignite when exposed to flame under standardized open-cup conditions. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Atomic absorption or optical emission spectroscopy after acid digestion to quantify total heavy metal concentration. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides in sample, followed by titration of liberated iodine with sodium thiosulfate. |
| Saponification Value | Back Titration | Ester hydrolysis with excess potassium hydroxide, followed by titration of unreacted alkali with hydrochloric acid. |
| Volatile Impurities (e.g., DINP isomers, solvents) | GC-MS | Identification and quantification of low-boiling impurities using gas chromatography coupled with mass spectrometric detection. |
