Manufacturing Quality Control of N,N-Bis(2-hydroxyethyl)ethylenediamine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state under natural light or standard illumination to determine whether it is a colorless to pale yellow transparent liquid, and check for any suspended particles or precipitates. |
| Content Determination | Acid-Base Titration / High-Performance Liquid Chromatography (HPLC) | - Acid-Base Titration: Utilizes the basic amino group in the sample reacting with a standardized acid (e.g., hydrochloric acid). The endpoint is determined using an indicator or potentiometric titration, allowing calculation of the main component content. - HPLC Method: Uses a reversed-phase column (e.g., C18) and UV detector (low wavelength, e.g., 210 nm), with external or internal standard method for quantification, suitable for high-purity analysis. |
| pH Value | pH Meter Measurement | Dissolve the sample in water (e.g., 1% aqueous solution), then measure the pH using a calibrated pH meter to evaluate its alkalinity. Typically exhibits weak alkalinity. |
| Moisture Content | Karl Fischer Titration | Uses the quantitative reaction between iodine and sulfur dioxide in methanol/pyridine with water. The moisture content is determined by coulometric titration, suitable for trace moisture detection. |
| Hydroxyl Value | Titration Method (Acetylation Method) | The sample reacts with acetic anhydride via esterification. After hydrolysis, the generated acetic acid is titrated with a standardized base to calculate the hydroxyl number, reflecting the hydroxyethyl content. |
| Colorimetry | Platinum-Cobalt Colorimetric Method (APHA Color) | Compare the sample visually against a platinum-cobalt standard color scale to assess color intensity, used to control product hue and ensure appearance quality. |
| Density | Density Meter Method / Specific Gravity Bottle Method | Measure the liquid density at a specified temperature (e.g., 20°C or 25°C) using a density meter or specific gravity bottle, used for physical property verification. |
| Refractive Index | Refractometer Method | Determine the refractive index of the sample using an Abbe refractometer under constant temperature conditions, serving as an auxiliary criterion for purity and composition. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion treatment, detect residual heavy metals such as lead, mercury, cadmium, and arsenic to ensure compliance with safety standards. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from impurity peaks using HPLC, detect and quantify related impurities (e.g., unreacted raw materials, oxidation products) via UV detection. |
| Thermal Stability | Thermogravimetric Analysis (TGA) or Differential Scanning Calorimetry (DSC) | Assess decomposition temperature and thermal stability by monitoring mass changes or thermal effects during heating. |
