Algorithm for Calculating the Protolytic Equilibrium Constants of Organic Acids in Isopropyl Alcohol
Tóm tắt
An algorithm is developed for calculating the dissociation constants of weak organic acids in isopropyl alcohol. The procedure is based on spectrophotometric data in the UV and visible regions without measuring the pH of the medium or using buffer solutions. A new way of determining analytical wavelengths in spectrophotometry is proposed. The original algorithm is tested experimentally for seven organic acids of different strengths, and the relative error in determining the dissociation constants does not exceed 1%.
