Manufacturing Quality Control of Trimethyl orthobutyrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color against APHA platinum-cobalt standard scale using 10 mm pathlength cell. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume by oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 degC | Refractometry | Measures bending of light through sample using calibrated Abbe refractometer or digital equivalent. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelength. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using silver indicator electrode and reference electrode. |
| Non-Volatile Matter | Gravimetric Analysis | Dries sample film at 105 degC to constant weight and determines residual solids mass. |
| Odor | Sensory Evaluation | Assesses off-odor presence by trained personnel against specification limits (pass/fail). |
| Appearance | Visual Inspection | Evaluates clarity and absence of suspended particles or phase separation in transparent container under controlled lighting. |
