Abstract:  Kinetic measurements were evaluated and the conclusions were drawn for relative rates of particular steps of the aldol condensation of butanal. Four kinetic models are compared: a semiempirical model of the first-order reaction; a model based on the assumption of constant concentration of carbanion; a model according to which carbanion is an intermediate and its concentration varies with time; a model equal to the preceding one with further assumption of irreversible formation of carbanion. Such a system of equations and rate constants has been selected which depictures the experimental material best and is in agreement with the present theoretical ideas on the operating mechanism.
