Manufacturing Quality Control of Adipic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Assay | Acid-Base Titration | Titrate aqueous adipic acid solution with standardized sodium hydroxide solution, using phenolphthalein as indicator. The adipic acid content is calculated based on the volume of alkali consumed. Suitable for rapid quantitative analysis of high-purity samples. |
| Appearance | Visual Inspection | Place the sample on a white background and observe under natural or standard lighting to determine whether it is a white crystalline powder, and to detect any impurities or discoloration. |
| Melting Point | Melting Point Determination (Capillary or Automatic Melting Point Apparatus) | Determine the temperature at which adipic acid transitions from solid to liquid. The melting point of pure adipic acid is approximately 152–154°C, used to assess purity. A narrower melting range indicates higher purity. |
| Moisutre Content (Loss on Drying) | Drying Method (Gravimetric) | Dry a specified amount of sample at 105°C until constant weight is achieved; moisture content is calculated from the weight loss, used to control residual moisture in the product. |
| Residue on Ignition | Sulfated Ash Test | The sample is carbonized, treated with sulfuric acid, and then ignited at high temperature. The weight of the residual residue is measured to evaluate the content of inorganic impurities. |
| pH Value | pH Meter Method | Prepare a defined concentration of adipic acid solution (e.g., 1% aqueous solution) and measure its pH using a calibrated pH meter to reflect its acidity and potential influence from impurities. |
| Heavy Metals | Sulfide Colorimetric Method (e.g., Lead) | Under weakly acidic conditions, heavy metal ions react with hydrogen sulfide to form colored precipitates, which are quantified by comparison with a standard lead solution, typically expressed as Pb. |
| Chlorides | Silver Nitrate Turbidity Method | Add silver nitrate to the sample solution; if chlorides are present, a white turbidity forms. Compare the turbidity with that of a standard chloride solution to control Cl⁻ content. |
| Sulfates | Barium Chloride Turbidity Method | Add barium chloride in a hydrochloric acid medium; sulfates form a white barium sulfate precipitate. Quantify SO₄²⁻ content by turbidity comparison. |
| Related Substances / Organic Impurities | High-Performance Liquid Chromatography (HPLC) | Use a C18 column with UV detection (approx. 210 nm) to analyze potential impurities such as glutaric acid, pimelic acid, or other homologues or by-products based on retention time and peak area. |
| Color (Colorimetry) | Platinum-Cobalt Color Scale Method | Compare the color of the sample solution with a platinum-cobalt standard color scale to assess yellowness, reflecting the presence of oxidized or colored impurities. |
