When adiponitrile is prepared by the reaction synhtesis adipic acid with ammonia small proportions of cyclopentanone are formed, and the impure compound can be isolated from the first runnings of the adiponitrile distillation see DE-A Published by Organic Syntheses, Inc.
The gaseous mixture leaving the reactor cyclopetanone through a filter and is then cooled and scrubbed in a tower through which methanol is pumped. Cyclopentanone is obtained in high yield and purity when this catalyst is employed in the novel process.

Cyclopentanone is quite volatile with ether vapor, and careful fractionation is necessary when ether is used for the separation of the. As part of an investigation of the Raman spectrum of cyclopentanone by Jones, Kartha and Mantsch (l) it became necessary to synthesize the title compounds. Catalytic amounts of weak bases such as sodium carbonate can carry out the ketonic decarboxylation of adipic acid into cyclopentanone selectively. This is in.
