WebThe meaning of ETHYL ACETOACETATE is a colorless liquid ester with pleasant odor important for its tautomerism [keto form CH3COCH2COOC2H5, enol form CH3C(OH)=CHCOOC2H5] and for the numerous condensations it can undergo —called also acetoacetic ester. WebAccording to our results, ethyl acetoacetate favors the keto form in methanol and in chloroform as opposed to acetylacetone which favors the enol form in both. In the gas phase, both favor the enol form, but the equilibrium constant is … WebMix 6 2 ml.
