Manufacturing Quality Control of Diethylene glycol monobutyl ether
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity (Main Component Content) | Gas Chromatography (GC) | Using a capillary column (such as DB-5 or HP-INNOWAX) with FID as the detector, quantification is performed using internal standard or external standard methods. This method effectively separates diethylene glycol butyl ether and its common impurities (such as monoethylene glycol butyl ether, triethylene glycol butyl ether, water, alcohols, etc.), allowing accurate determination of the main component content (typically ≥99%). |
| Water Content | Karl Fischer Titration | Uses Coulometric or Volumetric Karl Fischer reagent to quantitatively determine trace water in the sample by electrolysis of iodine and water reaction. Suitable for controlling water content (typically ≤0.1%), preventing it from affecting product stability and subsequent application performance. |
| Color (Appearance) | Platinum-Cobalt Colorimetry (APHA/Hazen) | The sample is visually compared or measured spectrophotometrically against a standard platinum-cobalt color scale, expressed in Hazen units (Pt-Co). Used to assess whether the product color meets industrial grade (typically ≤10 Hazen) or electronic grade (≤5 Hazen) requirements. |
| Acid Value (Acidity) | Acid-Base Titration | Using phenolphthalein as an indicator, the sample is titrated with a standard sodium hydroxide solution to determine free acids (such as organic acids, degradation products), with results expressed in mg KOH/g. Used to control acidic impurities caused by oxidation or hydrolysis (typically ≤0.01 mg KOH/g). |
| Boiling Point Range | Distillation Method (GB/T 7534 or ASTM D86) | Determines the boiling point range of the sample under atmospheric pressure using a precision distillation apparatus. The theoretical boiling point of diethylene glycol butyl ether is approximately 230–232°C, with controlled ranges typically between 228–234°C, used to identify high or low boiling point impurities. |
| Density (20°C) | Densitometry (Glass Float or Digital Densimeter) | Determine the density of the sample at 20°C using a precision densimeter. The standard density of diethylene glycol butyl ether is approximately 0.955–0.965 g/cm³, used to assist in assessing purity and batch consistency. |
| Evaporated Residue (Non-Volatile Matter) | Weighing Method (Drying to Constant Weight) | After evaporating the solvent at 105°C, the mass of the residue is weighed to calculate the percentage. Used to detect inorganic salts, polymers, or high-boiling-point impurities (typically ≤0.05%). |
| Impurity Profile (Trace Impurities) | Gas Chromatography-Mass Spectrometry (GC-MS) | Used for qualitative analysis of unknown impurities (such as ethylene glycol ether homologs, aldehydes, ketones, esters, etc.), combined with a standard library for structural confirmation. Commonly used for deep quality control of high-purity products (such as electronic grade). |
| UV Absorbance | UV-Visible Spectrophotometry | Determine the absorbance of the sample in the wavelength range of 200–400 nm, particularly at 220 nm and 254 nm, to detect impurities with conjugated structures (such as aldehydes, ketones, aromatic compounds). Ensures no light-absorbing impurities (typically A < 0.1). |
