Manufacturing Quality Control of Cellulose acetate phthalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acetyl Content | Acid-Base Titration | Hydrolysis of acetyl groups followed by titration of liberated acetic acid with standardized NaOH. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 500-600 C to oxidize organic matter, then sulfuric acid treatment and final ash weighing. |
| Viscosity (in acetone/water) | Capillary Viscometry | Measurement of flow time through a calibrated capillary tube under gravity to determine relative or intrinsic viscosity. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 550-600 C until constant weight to determine inorganic impurity content. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Quantification of trace metal elements after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Loss on Drying | Thermogravimetry | Weight loss measured after drying at 105 C for 2 hours to determine volatile content including moisture. |
| pH of 1% Aqueous Dispersion | Potentiometric Titration | Measurement of hydrogen ion activity using calibrated pH electrode in aqueous suspension. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate size distribution profile. |
| Assay (Purity) | UV-Vis Spectrophotometry | Quantification based on absorbance at characteristic wavelength after dissolution in suitable solvent. |
| Chloride Content | Argentometric Titration | Titration with standardized silver nitrate solution using potassium chromate indicator. |
| Free Acetic Acid | Gas Chromatography | Separation and quantification of volatile acetic acid using flame ionization detection. |
| Substituted Phthalate Content | HPLC-UV | Separation on reversed-phase column and UV detection of phthalic acid derivatives after hydrolysis. |
