Versatic Acid 5

 

 

Description

VersaticTM Acid 5 is the smallest possible tertiary carboxylic acid. Other chemical names are pivalic acid, 2,2- (or alpha,alpha-) di-methylpropionic acid, tri-methylacetic acid and neo-pentanoic acid. Its structure is represented as:

 

 

 

Versatic acid 5

 

 

Versatic Acid 5 is a white colourless solid at ambient temperatures, liquid at 40°C, and having a pungent odour.

 

 

Applications

Versatic Acid 5 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 branched Versatic structure combined with the tertiary nature of its alpha-carbon atom. This is especially demonstrated in comparison with its linear and secondary equivalents.

 

Versatic Acid 5 is used mainly in the form of its chloride, pivaloyl chloride, produced by reaction with e.g. phosgene, PCl3 or thionylchloride. Pivaloyl chloride is used as intermediate in the production of several peroxy-esters for polymer production, as intermediate for agrochemicals and for the production of semi-synthetic penicillin, e.g. amoxicillin.

Transportation and Storage

Information on transport, storage, suitable materials for tank construction, etc, is available from Hexion, via local representative or distributor.    

Versatic Acid 5 should preferably be stored between 45-64 ºC (minimum storage temperature 5ºC at which material will be solid) in conditions such that moisture is excluded, in the original containers kept tightly closed. Under these conditions the shelf life should be three years starting from the manufactured date.

 

Handling Precautions

For more detailed information on all aspects relating to Health, Safety and Handling, reference should be made to the Safety Data Sheet of Versatic Acid 5, which is available from your local Hexion representative or distributor. The precautions advised therein should be strictly observed.
