Manufacturing Quality Control of 2-N-BUTYLPROPANE-1,3-DIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; uses capillary column and temperature programming. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color to platinum-cobalt standard solutions; quantifies yellowness index via absorbance. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measures oscillation period of a U-shaped tube filled with sample to calculate density based on mass/volume relationship. |
| Refractive Index at 20 C | Refractometry (Abbe refractometer) | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Evaporates sample under controlled heat and vacuum, then weighs non-volatile residue relative to initial mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantifies metal content by measuring absorption of specific wavelength light by ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via silver nitrate titration using silver electrode to detect endpoint potential shift. |
| Aldehyde Impurities | GC-MS or Derivatization followed by HPLC-UV | Converts aldehydes to stable hydrazones; separates and quantifies using UV detection or mass-selective detection. |
| Non-Volatile Residue | Hot Plate Evaporation and Gravimetry | Evaporates fixed volume on hot plate, dries to constant weight, and determines residue mass per unit volume. |
| Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in solution using sodium D-line light source. |
