Manufacturing Quality Control of 1,1'-Oxydi-2-propanol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color and clarity under natural light or standard illumination; it should be a colorless, transparent liquid. |
| Color | Platinum-Cobalt Colorimetric Method (GB/T 3143) | Compare the sample color against platinum-cobalt standard solutions to determine the color value (unit: Hazen or APHA), assessing purity. |
| Content (Main Component) | Gas Chromatography (GC) | Separate using capillary column gas chromatography with flame ionization detection (FID); quantify DPG content by internal or external standard method. |
| Moisture | Karl Fischer Titration | Based on the reaction of iodine with sulfur dioxide in methanol with water, precisely measure moisture content using coulometric or volumetric methods. |
| Acid Value | Acid-Base Titration | Titrate the sample with standardized potassium hydroxide ethanol solution using phenolphthalein as indicator; calculate mg of KOH required to neutralize one gram of sample (mg KOH/g). |
| Density | Density Meter or Digital Density Analyzer | Measure sample density at specified temperature (e.g., 20°C) using a hydrometer or oscillating U-tube digital densitometer. |
| Refractive Index | Refractometry (Abbe Refractometer) | Measure refractive index using an Abbe refractometer at standard temperature (usually 20°C or 25°C), used for identification and purity assessment. |
| Boiling Range | Distillation Method | Perform atmospheric distillation using a standard apparatus; record initial and final boiling points to evaluate whether the boiling range meets specifications. |
| Impurities (e.g., Monopropylene Glycol, Tripropylene Glycol) | Gas Chromatography (GC) | Use GC to effectively separate DPG from its homologs (e.g., MPG, TPG); identify components by retention time and quantify via peak area. |
| Residual Volatiles | Thermogravimetric Analysis (TGA) or Gravimetric Method | Heat the sample to constant weight at a specified temperature and determine the percentage of residue remaining after volatilization. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measure trace metal contents such as lead, arsenic, and cadmium to ensure compliance with pharmacopeial or food-grade standards. |
| pH Value (aqueous solution) | pH Meter Measurement | Prepare a certain concentration aqueous solution (e.g., 10%), use a calibrated pH meter to measure acidity or alkalinity; typically neutral or slightly acidic. |
