Versatic™ Acid 10


VersaticTM Acid 10 is a synthetic, highly branched-C10 tertiary carboxylic acid. Versatic Acid 10 is also known as neodecanoic acid. Its structure may be represented as:

Versatic acid 10

R1 and R2 are alkyl groups. Versatic Acid 10 contains a total of 10 Carbon atoms. Versatic Acid 10 is a water-like clear product that is liquid at ambient temperature.


Versatic Acid 10 is a key intermediate in the manufacture of a variety of products, which typically show excellent hydrolytic stability and resistance to various chemical agents. This is due to the steric hindrance created by the highly branched Versatic structure combined with the tertiary nature of its alpha-carbon atom. This is especially demonstrated in comparison with its linear and secondary-C10 equivalents.

Versatic Acid 10 can be used in its acid form, but for many applications the product is typically first converted into an acid chloride or metal salt. The acid chloride is produced by reaction with, for example, phosgene or PCl3 and is used in the production of peroxides for polymer production. Metal salts, e.g. Cobalt, Copper or Zinc salts of Versatic Acid 10 are used in applications such as tire adhesives, paint driers, PVC heat stabilisers, chemical processing catalysts, unsaturated polyester cure catalysts, wood preservatives and fuel additives. Additionally, Versatic Acid 10 acid is a very effective metal extraction agent that is particularly suitable for Nickel. The acid can also be used as corrosion inhibitor in synthetic lubricants.
