Manufacturing Quality Control of 1,5-Pentanediol diacrylate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,5-pentanediol diacrylate peak area against a calibration curve using an internal or external standard. |
| Acid Value | Acid-Base Titration with KOH ethanol solution | Measures free carboxylic acid content by titration with standardized potassium hydroxide in ethanol using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation followed by Titration | Determines residual hydroxyl groups via acetic anhydride derivatization, followed by back-titration of unreacted anhydride. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water based on iodine generation proportional to water content in the sample. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color intensity to APHA platinum-cobalt standards or measures absorbance at 430 nm in a 10 mm cell. |
| Viscosity (at 25 C) | Rotational Viscometry | Measures resistance to flow under controlled shear rate using a calibrated spindle and rotational viscometer. |
| Refractive Index (at 25 C) | Refractometry | Determines ratio of light velocity in air vs. sample using a calibrated digital refractometer at specified temperature. |
| Specific Gravity (at 25/25 C) | Digital Density Meter or Pycnometer | Compares density of sample to water at 25 C using oscillating U-tube principle or precise mass/volume measurement. |
| Acrylate Monomer Impurities (e.g., acrylic acid, hydroquinone) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates and identifies volatile impurities based on retention time and characteristic mass spectra fragmentation patterns. |
| Residual Solvents (e.g., toluene, ethyl acetate) | Headspace Gas Chromatography (HS-GC) with FID | Quantifies volatile solvents by equilibrating sample in sealed vial, injecting headspace gas, and detecting via flame ionization. |
| Peroxide Value | Iodometric Titration | Measures hydroperoxides by reaction with potassium iodide under acidic conditions, followed by titration of liberated iodine with sodium thiosulfate. |
| UV Absorbance (at 275 nm) | UV-Vis Spectrophotometry | Detects conjugated impurities or degradation products by measuring absorbance in methanol or neat sample at 275 nm. |
