| Coatings | Film-forming aid or leveling agent | Dispersion and curing |
Manufacturing Quality Control of Hexaethylene glycol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and transparency under natural or standard lighting to determine if it is a colorless, transparent liquid, and check for suspended particles or impurities. |
| Color Intensity | Platinum-Cobalt Colorimetric Method (APHA) | Compare the sample with a platinum-cobalt standard color scale to quantitatively assess the intensity of color, used for evaluating purity and degree of oxidation. |
| Purity | Gas Chromatography (GC) | Separation using a capillary column and detection by FID; calculate the content of hexaethylene glycol as the main component via peak area normalization or external standard method. |
| Moisture Content | Karl Fischer Titration | Utilize the quantitative reaction of iodine and sulfur dioxide with water in methanol; measure trace moisture based on electricity consumption or reagent usage. |
| pH Value | pH Meter Measurement | Dissolve hexaethylene glycol into an aqueous solution (e.g., 10%), then use a calibrated pH meter to measure acidity or alkalinity, assessing the level of acidic impurities. |
| Hydroxyl Value | Titration Method (Acetylation) | React sample with acetic anhydride to acetylate hydroxyl groups; after hydrolysis, titrate the liberated acetic acid with standard alkali solution to calculate hydroxyl value (mg KOH/g). |
| Acid Value | Acid-Base Titration | Dissolve the sample in a neutral solvent (e.g., ethanol), then titrate free acids with standard potassium hydroxide solution to determine acid value (mg KOH/g). |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and analyze concentrations of heavy metals such as lead, iron, and copper to ensure compliance with pharmaceutical or electronic-grade purity requirements. |
| Residue on Ignition (Ash Content) | Gravimetric Method (Ignition Residue) | Iignite the sample to constant weight in a high-temperature muffle furnace, then weigh the residue to calculate the content of non-volatile inorganic matter. |
| Residual Ethylene Oxide / Ethylene Glycol | Gas Chromatography-Mass Spectrometry (GC-MS) | Detect possible residual ethylene oxide, ethylene glycol, and other oligomeric impurities from the synthesis process to ensure product safety. |
