Thermometry-Enthalpimetry

Abstract

The acid-base equilibria of succinediamidoxime (SIDA) were studied by means of potentiometric and thermometric techniques. RefinedpK values (pK1=4.19;pK2=5.82;pK3=10.70;pK4= 10.82) and neutralization enthalpies were obtained using several computer programs (GRAN, MINIQUAD and MINITERM).

Titration errors and thermodynamic parameters of SIDA are compared with the corresponding values obtained previously for other amidoximes.

Zusammenfassung

Säure-Basen-Gleichgewichte von Succindiamidoxim (SIDA) wurden mittels potentiometrischer und thermometrischer Techniken untersucht. VerbessertepK-Werte (pK1=4.19;pK2=5.82;pK3=10.70;pK4=10.82) und Neutralisationsenthalpien wurden unter Verwendung einiger Computerprogramme (GRAN, MINIQUAD, MINITERM) erhalten. Titrationsfehler und thermodynamische Parameter von SIDA werden mit entsprechenden Werten verglichen, die in früheren Arbeiten für andere Amidoxime erhalten wurden.

Резюме

Потенциометрически м и термометрическим методами изучено кис лотно-основное равновесие для сукци ндиамидоксима. Испол ьзуя несколько компьютер ных программ (Гран, Миниквад и Минитерм) б ыли получены улучшен ные значенияpK(pK1=4, 19;рK2=5,82;рK3=10,70 ирK4=10,82) и энтальпии р еакции нейтрализаци и. Ошибки титрования и термодинамические п араметры для сукцинд иамидоксима сопоставлены с таков ыми для других амидоксимов.
