| Coatings and Paints | Resin solvent for focused applications | Dissolves acrylic, epoxy, and alkyd resins; adjusts coating viscosity and drying rate |
| Ink Industry | Printing ink solvent | Controls ink drying rate; prevents plate drying and screen clogging during printing; improves printability |
| Cleaning Industry | Raw material for hard-surface cleaners | Acts as a coupling agent and solvent in glass cleaners and multi-purpose cleaners to enhance soil removal and solubilization |
| Electronics Industry | Solvent for electronic chemicals | Used in photoresist stripper formulations to remove residual photoresist, leveraging its high boiling point and solvency |
| Chemical Industry | Chemical reaction intermediate | Serves as an organic synthesis feedstock for producing other ether or ester derivatives |
| Agrochemical Industry | Agrochemical adjuvant | Functions as a component of emulsifiers and dispersants in agrochemical formulations to improve formulation stability and wetting performance |
Manufacturing Quality Control of DI(PROPYLENE GLYCOL) BUTYL ETHER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (Assay) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric or Volumetric) | Electrochemical titration where iodine reacts stoichiometrically with water in an anhydrous pyridine-methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities by standardized sodium hydroxide solution; endpoint detected by color change. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity to platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Density at 20 °C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped glass tube filled with the sample. |
| Refractive Index at 20 °C | Abbe Refractometer | Determination of refractive index based on critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporation of a known sample mass to dryness under controlled temperature, followed by weighing of residual solids. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantification of trace metals by measuring absorption of element-specific hollow cathode lamp radiation after sample mineralization. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride ions on an anion-exchange column and quantitative detection via electrical conductivity of eluent. |
| Residual Solvents (e.g., Propylene Glycol, Butanol) | Gas Chromatography–Mass Spectrometry (GC-MS) | Identification and quantification of volatile impurities using retention time and characteristic mass fragments relative to internal standards. |
| Appearance (Clarity & Particulates) | Visual Inspection against White/Black Background | Subjective assessment of liquid clarity and presence of suspended particles under controlled lighting conditions. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determination of lowest temperature at which vapors above the sample ignite momentarily when exposed to a flame under standardized closed-cup conditions. |
