Phenol exhibits keto-enol tautomerism with its unstable keto tautomer … WebHigh-performance liquid chromatography of some ketones at −20–−60 °C achieved the separation of keto and enol tautomers. The ratios of keto and enol forms in different conditions were determined for β-diketones. Cyclohexanone also gave a small peak which was possibly attributed to enol tautomer along with a large peak of keto tautomer. hinemos ha on aws
