General description

Acrylic acid (AAc) is a colorless, unsaturated carboxylic acid. It is miscible in water and alcohol. It often finds application as an chemical intermediate.


AAc is used in preparing monodispersed poly (N-isopropylacryamide) (PNIPAM)/AAc microgels. AAc has been plasma-deposited on surfaces for cell culture applications. Surface modification of poly(ethylene terephthalate) (PET) films via UV-induced graft copolymerization with AAc has been reported. AAc is used primarily as an intermediate in the production of acrylates.

Certificado de Análisis

Certificado de origen

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is Product 147230, Acrylic acid soluble in?

    According to The chemicals encyclopedia published by the Royal Society of Chemistry: 13th Edition, Acrylic acid is miscible with water, alcohol, and ether.

  4. How can the inhibitor be removed from Product 147230, Acrylic Acid?

    This product contains monomethyl ether hydroquinone as the inhibitor, which cannot be removed with an inhibitor remover. The effects of the inhibitor can be negated by adding excess initiator.

  5. What is the viscosity of Product 147230, Acrylic Acid?

    According to our supplier the viscosity is 1.232 cP at 25 C. However, we do not test the viscosity since it is not one of our specifications.

  6. What is the bulk density of from Product 147230, Acrylic Acid?

    According to our supplier the bulk density is 8.75 lb/gal at 20 deg C.

  7. What is the freezing point of from Product 147230, Acrylic Acid?

    According to literature the freezing point is 13 C. If freezing occurs do not remove the acrylic acid from a partially-thawed bottle. The remaining material would be seriously under-inhibited.
