Industrial Applications of Nonaethylene glycol
| Industry | Application | Process |
|---|---|---|
| Chemical | Solvent | Used to dissolve polymers and organic compounds, serving as a reaction medium or cleaning agent |
| Chemical | Chemical synthesis intermediate | Participates in the synthesis of ethers and polyethers, acting as a linking unit to construct long-chain molecules |
| Pharmaceutical | Pharmaceutical excipient | Used as a solubilizer or stabilizer in certain drug formulations to improve drug solubility |
| Materials Science | Polymer additive | Incorporated into polymer systems to adjust viscosity, flexibility, or hygroscopicity |
| Analytical Chemistry | Chromatographic reagent | Used as a stationary phase or modifier in gas or liquid chromatography to enhance separation efficiency |
Manufacturing Quality Control of Nonaethylene glycol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color, transparency, and presence of mechanical impurities under natural or standard lighting conditions. |
| Color | Platinum-Cobalt Colorimetric Method (GB/T 3143) | Compare the sample with a platinum-cobalt standard color scale to quantitatively assess yellowness, indicating oxidation or impurity levels. |
| Purity / Active Ingredient Content | High-Performance Liquid Chromatography (HPLC) | Use refractive index or evaporative light scattering detection, with reverse-phase or gel chromatographic columns for separation; quantify active ingredient content via external standard or area normalization method. |
| Molecular Weight Distribution | Gel Permeation Chromatography (GPC/SEC) | Separate components by molecular weight using gel columns of different pore sizes; compare with standards to determine average molecular weight and polydispersity index (PDI). |
| Moisture Content | Karl Fischer Titration | Use electrochemical titration principle to accurately measure free water content in samples, suitable for trace moisture analysis. |
| pH Value | pH Meter Method | Dissolve sample in water and measure solution acidity or alkalinity using a calibrated pH meter to evaluate compliance with neutrality requirements. |
| Ignition Residue | Gravimetric Method | Weigh inorganic residue after high-temperature ignition of the sample to evaluate total inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and analyze concentrations of heavy metal elements such as lead, arsenic, mercury, and cadmium to ensure compliance with safety limits. |
| Ethylene Oxide / 1,4-Dioxane Residues | Headspace Gas Chromatography (HS-GC) | Detect volatile toxic by-products like ethylene oxide or 1,4-dioxane potentially remaining from synthesis process, using FID detector for quantification. |
| Hydroxyl Value | Titration Method (Acetylation) | React hydroxyl groups with acetylating agent and back-titrate excess reagent to calculate hydroxyl content per unit mass, indirectly reflecting degree of polymerization. |
