Industrial Applications of 16669-27-5
| Industry | Application | Process |
|---|---|---|
| Coatings & Inks | Used as a high-molecular-weight acrylate monomer to enhance film flexibility, water resistance, and film-forming properties | Free-radical polymerization; employed as a comonomer with methyl methacrylate, butyl acrylate, etc., to synthesize low-Tg acrylic resins |
| Cosmetics | Functions as a film former and hydrophobicity modifier in mascara, waterproof foundation, and long-wear color cosmetic formulations | Blended with waxes and silicones in emulsion or anhydrous systems, then dispersed and stabilized via cold mixing or temperature-controlled homogenization |
| Lubricants & Functional Fluids | Used as a high-performance synthetic lubricant additive to improve oil film strength and high-temperature stability | Blended with polyol ester base oils or polyalphaolefins (PAO), followed by vacuum dehydration and homogeneous mixing to formulate specialty lubricants |
| Plastic Modification | Acts as an internal plasticizing comonomer to improve the impact resistance and melt processability of PMMA | Subjected to bulk or suspension polymerization with methyl methacrylate; comonomer ratio (typically ≤5 wt%) is controlled to modulate backbone flexibility of the copolymer |
Manufacturing Quality Control of 16669-27-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of free carboxylic acid groups by standardized potassium hydroxide solution, using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation followed by Titration | Esterification of hydroxyl groups with acetic anhydride, followed by back-titration of unreacted anhydride with NaOH. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation and titration of iodine to quantitatively react with water in the sample. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Measurement of yellowness intensity relative to platinum-cobalt standards using spectrophotometer or comparator. |
| Refractive Index | Refractometry at 20 degC | Determination of light bending angle in sample at specified temperature using calibrated Abbe refractometer. |
| Density at 25 degC | Digital Density Meter or Pycnometer | Mass per unit volume measured via oscillating U-tube principle or calibrated glass pycnometer. |
| Viscosity (40 degC) | Capillary Viscometry (e.g., Ubbelohde) | Measurement of flow time through calibrated capillary under gravity, converted to kinematic viscosity. |
| Unsaturation (Iodine Value) | Wijs Method (Halogen Addition) | Reaction of iodine monochloride with double bonds, followed by titration of unreacted halogen with sodium thiosulfate. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass at controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion and matrix-matched calibration using hollow cathode lamp. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
