Abstract: The dissociation constants of phenol, 2−methylphenol, 3−methylphenol, 4−methylphenol, and 4−ethylphenol have been determined by potentiometric titration in a electrochemical cell with glass electrode at 25 oC in water and in the mixtures of acetonitrile and water where the following volume fractions (before mixing) of acetonitrile were used: 0.10, 0.20, and 0.30. The ionic strength of the solutions was adjusted to be 0.1 mol dm−3 using KCl. The dissociation constants were calculated by using the commercial Hyperquad 2008 program. The obtained results are in good concordance withliterature values.Key words: Phenols, acid dissociation constant, potentiometric method.Bazı Substitue Fenollerin Ayrışma Sabitlerinin Asetonitril-SuKarışımlarında Potansiyometrik Metotla TayiniÖzet: Fenol, 2-metilfenol, 3-metilfenol, 4-metilfenol ve 4-etilfenol'ün ayrışma sabitleri %10-20-30 oranlarında hazırlanan asetonitril –su karışımında 25 oC potansiyometrik olarak elektrokimyasal hücrede elektrot ile tayin edilmiştir.Titrasyon çözeltilerinde iyonik şiddet KCl kullanılarak 0.1 mol dm−3 olarak ayarlanmıştır. Ayrışma sabitleri ticari bir program olan Hyperquad 2008 ile hesaplanmıştır. Elde edilensonuçlar literatürdeki değerlerle uyumluluk göstermektedir.Anahtar kelimeler: Fenol, asidik ayrışma sabiti, potansiyometrik yöntem. |
