| Industry | Application | Process |
|---|---|---|
| Chemical | Solvent | Used as a solvent for coatings, inks, and resins, offering excellent solvency and volatility control |
| Printing | Ink additive | Improves ink flow and drying rate, enhancing printability |
| Electronics | Cleaning agent | Applied to clean semiconductors and electronic components, removing organic residues |
| Coatings | Coating additive | Functions as a leveling agent and defoamer to improve coating surface quality |
| Textiles | Textile auxiliary | Used in dyeing and finishing processes to improve fiber wettability and uniformity |
| Pharmaceuticals | Pharmaceutical intermediate | Serves as an intermediate raw material in the synthesis of certain drugs or active pharmaceutical ingredients |
| Agrochemicals | Pesticide adjuvant | Enhances dispersion and substrate adhesion of pesticide formulations, improving efficacy |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities; endpoint detected potentiometrically or with phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 430 nm | Compares sample color to APHA platinum-cobalt standard scale using calibrated visual or instrumental method. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 degC | Refractometry | Measures bending of light through sample at specified temperature to infer purity and composition. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation | Evaporates known volume at 105 degC; residue weight determined by difference before and after drying. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration endpoint. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Digests sample with nitric acid, then measures absorbance of specific metal wavelengths in flame or graphite furnace. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Extracts volatile solvents into headspace; analyzes vapor phase using GC-FID or GC-MS. |
| Aldehyde Content | Spectrophotometry after reaction with DNPH | Derivatizes aldehydes to hydrazones; measures absorbance at ~450 nm proportional to concentration. |
| Viscosity at 25 degC | Rotational Viscometry | Measures resistance to flow under controlled shear rate using spindle rotation in constant-temperature bath. |
