Determination of acid dissociation constant of degradable tetrabromophenolphthalein ethyl ester by capillary zone electrophoresis.

An acid dissociation constant of tetrabromophenolphthalein ethyl ester (TBPE) was determined through the measurement of electrophoretic mobility by capillary zone electrophoresis (CZE). Although TBPE is degradable in acidic pH region and it gradually degraded at pH conditions around and below its pKa values in the time scale of the CZE measurement, equilibrium species of interest were detected ...

Simultaneous spectrophotometric analysis of aliphatic amines utilizing thermochromism of charge-transfer complexes with tetrabromophenolphthalein ethyl ester.

Aliphatic amines, such as n-hexylamine (primary), di-n-hexylamine (secondary) and tri-n-hexylamine (tertiary amine), react with tetrabromophenolphthalein ethyl ester molecules (TBPEH) to form reddish or red-violet charge-transfer complexes (CT complexes) in 1,2-dichloroethane (DCE). The absorption maxima of the CT complexes with all primary amines occur at around 560 nm, with secondary amines a...

Ion association titration for the determination of local anesthetics in pharmaceuticals with tetrabromophenolphthalein ethyl ester as an indicator.

Solvent extraction–spectrophotometries based on ion association formation have been established for the improvement of the sensitivity for the determination of ionic compounds such as anionic and cationic surfactants using hydrophobic dye ions. For example, anionic surfactants were determined using Methylene Blue,1 Ethyl Violet,2 Co(III)-5-Cl-PADAP3 and Malachite Green.4 Bromocresol Green,5 2,6...

Determination of Sulfate Ion with 2-Aminoperimidine Hydrobromide Using an Optode Based on Tetrabromophenolphthalein Ethyl Ester Membrane.

An optode method for the determination of sulfate ion was developed. The optode membrane is 2-nitrophenyl octyl ether-plasticized poly(vinyl chloride) membrane containing tetrabromophenolphthalein ethyl ester. The method is based on formation of an ion associate between the excess of 2-aminoperimidine hydrobromide (Ap) and sulfate ion in the sample solution, and detection of the concentration o...
