FAQ - Technical & Supply Chain

  • Q:

    What is Vinyl Chloroacetate used for?

    A: Vinyl Chloroacetate is mainly used as a reactive vinyl ester monomer for functional copolymers, acrylic and ethylene-based elastomers, dyeable acrylic fibers and water-resistant films. Its chloroacetate group provides a reactive site for later crosslinking or modification, so the comonomer system and inhibitor requirement should be confirmed with the current product-specific specification.
  • Q:

    How is Vinyl Chloroacetate different from Vinyl Acetate?

    A: Vinyl Chloroacetate contains a chloroacetate group and has CAS 2549-51-1, while Vinyl Acetate has CAS 108-05-4. The chlorine-containing ester group makes Vinyl Chloroacetate useful as a functional or crosslinkable monomer, but it also changes toxicity, handling, inhibitor requirements and process suitability, so the two monomers are not interchangeable.
  • Q:

    Is commercial Vinyl Chloroacetate normally supplied with an inhibitor?

    A: Often yes. Commercial material may contain MEHQ or another stated polymerization inhibitor, and the concentration is part of the offered grade. Do not assume an inhibited and inhibitor-free product are interchangeable; confirm inhibitor identity and level before process approval.
  • Q:

    What should be confirmed before ordering and storing Vinyl Chloroacetate?

    A: Confirm GC assay, inhibitor type and concentration, water, acidity, color and any process-specific impurity limits. State quantity, packaging and storage-temperature requirement. Vinyl Chloroacetate is normally a colorless liquid and is typically stored refrigerated around 2-8 degrees Celsius with the stated inhibitor, tightly closed and away from heat, light and moisture.
  • Q:

    What transport classification applies to Vinyl Chloroacetate?

    A: Vinyl Chloroacetate is commonly transported as UN 2589, Hazard Class 6.1 toxic liquid, Packing Group II, and it has a flammable-liquid flash point around 51 degrees Celsius. Confirm the exact classification, subsidiary hazards and approved packaging with the current product-specific safety information and destination requirements.
