Classification: 562/517

Preparation by carbonylation:

(under subclass 512) Processes wherein the acyclic carboxylic acid is produced through formation of a carboxyl group on an acyclic organic compound by reaction with carbon monoxide.

(1) Note. See subclasses 597 and 609 for carbonylation of inorganic compounds to produce oxalic and formic acids, respectively.
