Kumari, Renu; Singh, R. T. published the artcile< Studies on the effect of dielectric constants of aquo-DMF solvent- system of the solvolysis products of nicotinates>, Reference of 93-60-7, the main research area is dimethyl formamide nicotinate solvolysis dielec constant.
From the enhancement observed in ΔG* values with simultaneous decrease in the values of ΔH and ΔS* of the reaction, it is concluded that the organic co-solvent DMF (DMF) acts as entropy controller and enthalpy stimulator solvent for alkali catalyzed solvolysis of Me nicotinate. Form the evaluated values of water mols. associated with the activated complex of the reaction which are found to increase with increase in the temperature of the reaction, it is inferred that the bimol. mechanistic path is changed to unimol. in presence of the organic component (DMF) of the reaction media. The numerical value of Iso-Kinetic temperature of the reaction which comes to be nearly 287.5 (below 300) indicates that there is weak but considerable solvent-solute interaction in the aquo-DMF solvent system.
