Manufacturing Quality Control of 1,4-Butanediol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity / Main Component Content | Gas Chromatography (GC) | Capillary column gas chromatography with FID detector is used to quantitatively analyze the content of 1,4-butanediol. Purity is calculated using internal or external standard methods. |
| Moisture | Karl Fischer Titration | Utilizes the quantitative reaction between Karl Fischer reagent and water in the sample. Moisture content is determined by potentiometric titration or coulometric method, suitable for trace water detection. |
| Color | Platinum-Cobalt Color Scale (Pt-Co) | Visual or spectrophotometric comparison of the sample with standard platinum-cobalt solutions to evaluate color intensity, indicating the degree of oxidation or degradation impurities. |
| Acid Value | Acid-Base Titration | Free acids in the sample are titrated with a standard potassium hydroxide ethanol solution using phenolphthalein as indicator. Acid value is expressed as mg KOH/g. |
| Hydroxyl Value | Acetylation Method + Titration | The sample reacts with acetic anhydride to form ester. The excess acetic anhydride is hydrolyzed and then titrated with NaOH. Hydroxyl content is calculated by difference and converted to hydroxyl value (mg KOH/g). |
| Density | Density Meter or Digital Density Analyzer | Density is measured at a specified temperature (typically 20°C or 25°C) using a glass hydrometer or oscillating digital density meter. |
| Refractive Index | Abbe Refractometer Method | The refractive index of the sample is measured using an Abbe refractometer at standard temperature (e.g., 20°C), used for rapid identification and auxiliary purity assessment. |
| Boiling Range / Distillation Range | Distillation Method | The temperature range from initial boiling point to dry point is determined using a standard distillation apparatus to evaluate volatile impurities and product consistency. |
| Heavy Metals (e.g., Pb, As) | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, trace heavy metal elements are determined using atomic absorption spectroscopy or inductively coupled plasma mass spectrometry (ICP-MS). |
| Organic Impurities (e.g., γ-Butyrolactone, THF) | Gas Chromatography-Mass Spectrometry (GC-MS) or High-Performance Liquid Chromatography (HPLC) | GC-MS or HPLC is used to separate, identify, and quantify potential by-products or degradation products (e.g., γ-butyrolactone, tetrahydrofuran), enabling qualitative and quantitative analysis. |
