Manufacturing Quality Control of Triethylene glycol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | The sample is placed in a colorless transparent glass container and visually examined under natural light or standard illumination to determine whether it is a colorless, transparent liquid, and to detect the presence of suspended particles or precipitates. |
| Color | Platinum-Cobalt Color Scale (GB/T 3143 or APHA) | The sample is compared visually with standard platinum-cobalt solutions to determine its color value, used to assess product purity and degree of oxidation. |
| Purity (Main Component Content) | Gas Chromatography (GC) | A capillary column gas chromatograph is used with internal or external standard methods to determine the content of triethylene glycol, offering high resolution and accuracy. |
| Water Content | Karl Fischer Titration | Utilizes the quantitative reaction of iodine and sulfur dioxide in methanol with water; moisture content is determined via coulometric or volumetric titration. |
| pH Value | pH Meter Method | Aqueous solution of triethylene glycol (e.g., 1:10 dilution) is prepared and its acidity or alkalinity is measured using a calibrated pH meter. |
| Acid Value | Acid-Base Titration | The sample is titrated with a standard potassium hydroxide ethanol solution using phenolphthalein as an indicator; the acid value is expressed as milligrams of KOH required to neutralize one gram of sample (mg KOH/g). |
| Density | Densitometer or Pycnometer Method | At a specified temperature (e.g., 20°C), the mass per unit volume is measured using a densitometer or pycnometer to verify material consistency. |
| Refractive Index | Refractometry | The refractive index of the sample is measured at a standard temperature using an Abbe refractometer, serving as an auxiliary criterion for purity and composition. |
| Residue on Ignition | Gravimetric Method | The sample is incinerated at high temperature, and the residual mass is weighed to calculate the percentage of residue, reflecting the level of inorganic impurities. |
| Ultraviolet Absorption | UV-Visible Spectrophotometry | Absorbance is measured at specific wavelengths (e.g., 220 nm, 275 nm) to evaluate the presence of organic impurities or oxidation by-products. |
