Abstract: Several derivatives of salicylic acid have been synthesized by the condensation reaction of methyl salicylate with α,ω-diols and α,ω-diamines, and the acidity constants of five newly prepared derivatives have been determined in 61.10% aqueous ethanol using potentiometric titration method. In order to avoid calibration of pH-meter, the standard potential of glass electrode was determined from the titration data. The results obtained are discussed with regard to different resonance effects of the ester oxygen an…
