Manufacturing Quality Control of 1,3-Butanediol
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a colorless transparent glass container and visually inspect its color and clarity under natural light or standard light source to determine whether it is a colorless transparent liquid. |
| Content (Purity) | Gas Chromatography (GC) | Use a gas chromatograph with an appropriate polarity capillary column to separate components, and detect using a flame ionization detector (FID). Quantify the 1,3-butanediol content using external standard or internal standard methods. |
| Moisture | Karl Fischer Titration | Utilize the quantitative reaction between iodine and sulfur dioxide in an anhydrous environment with water, and measure moisture content using potentiometric titration or coulometric methods. Suitable for trace moisture detection. |
| Density | Pycnometer Method or Digital Density Meter Method | Measure the density of the sample at a specified temperature (e.g., 20°C) using a pycnometer or oscillating digital density meter. Used as an auxiliary method to assess purity. |
| Refractive Index | Refractometer Method | Use an Abbe refractometer to measure the refractive index of the sample at standard temperature (e.g., 20°C), which serves as a physical constant for identification and purity evaluation. |
| Acid Value | Acid-Base Titration | Dissolve the sample in ethanol and titrate with standard sodium hydroxide solution using phenolphthalein as an indicator. Calculate the amount of KOH (in mg) consumed per gram of sample to reflect the content of acidic impurities. |
| Color | Platinum-Cobalt Colorimetric Method | Compare the sample visually or instrumentally with platinum-cobalt standard color scales to determine the depth of color and evaluate the color grade of the product. |
| Residual Solvents | Gas Chromatography (GC) | Analyze by headspace or direct injection using GC-FID to detect possible residual organic solvents (e.g., methanol, acetone, ethanol), complying with pharmacopoeia or customer requirements. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | After sample digestion, use atomic absorption spectrometry or inductively coupled plasma mass spectrometry to determine the content of heavy metals such as lead, arsenic, and cadmium. |
| Hydroxyl Value | Acetylation Method + Back Titration | React the sample with an acetylation reagent (e.g., acetic anhydride) to form esters and release acetic acid. Use a standard alkali solution to back-titrate unreacted acid and calculate the hydroxyl content. |
