Industrial Applications of Acrylic anhydride
| Industry | Application | Process |
|---|---|---|
| Personal Care | Used as a crosslinker in cosmetic formulations to enhance product stability | Mixed with polymers to form crosslinked network structures |
| Coatings | Used in the synthesis of high-performance coatings and resins to improve adhesion and durability | Participates as a monomer in polymerization reactions to produce polyacrylate resins |
| Pharmaceuticals | Used in the synthesis of pharmaceutical intermediates, including certain antibiotics and antiviral agents | Serves as a key intermediate in multi-step synthetic routes |
| Textiles | Used in manufacturing functional textiles, such as water- and soil-repellent finishing agents | Reacts with fiber materials to introduce functional groups |
| Water Treatment | Used in the production of water treatment chemicals, including flocculants and dispersants | Acts as a crosslinker or functional monomer in polymerization reactions |
| Plastics | Used in the production of high-performance plastics and elastomers to enhance material properties | Participates in copolymerization reactions to improve thermal stability and mechanical performance |
Manufacturing Quality Control of Acrylic anhydride
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and transparency under natural or standard lighting to determine if it is a colorless to pale yellow transparent liquid, and check for suspended matter or precipitates. |
| Content (Purity) | Gas Chromatography (GC) | Use a capillary gas chromatograph with internal or external standard method to measure the peak area of acryloyl anhydride and calculate its purity. Offers high resolution and sensitivity. |
| Acid Value (or Free Acid Content) | Acid-Base Titration | Titrate free acids (e.g., acrylic acid) in the sample with a standardized sodium hydroxide solution, using phenolphthalein indicator or potentiometric titration to determine the endpoint; calculate acid value (mg KOH/g). |
| Water Content | Karl Fischer Titration | Quantitatively determine trace moisture in the sample based on an electrochemical reaction. Suitable for low-level water detection (ppm range) with high accuracy. |
| Density | Densimeter or Pycnometer Method | Measure mass per unit volume at a specified temperature (e.g., 20°C) to verify consistency of the substance. |
| Refractive Index | Refractometry | Determine refractive index using an Abbe refractometer at standard temperature, used as an auxiliary parameter for identification and purity assessment. |
| Color | Platinum-Cobalt Color Scale (APHA Color) | Compare the sample against a standard platinum-cobalt color series to evaluate color intensity, reflecting impurities or degree of oxidation. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separate and identify volatile by-products or residual solvents in the sample for impurity profile analysis. |
| Peroxide Content | Iodometric or Colorimetric Method | Detect peroxides that may form during storage to prevent risks of polymerization or safety hazards. |
| Freezing Point / Melting Point | Melting Point Determination | Measure the freezing point of acryloyl anhydride to assess purity and presence of high-melting impurities. |
