Procedure

Disclosed is a process for the conversion of off-color cyclopropanecarboxylic acid (CPC-Acid) to CPC-Acid having a color value (platinum-cobalt scale) of less than about 10 by the steps of (1) heating off-color CPC-Acid produced by the oxidation of cyclopropanecarboxaldehyde with molecular oxygen with a strong acid; and (2) distilling the mixture of step (1) to obtain CPC-Acid having a color value of less than about 10 as the distillate product.
