Kyseliova Y. Heterogeneous association with anions phenolsulfonephthalein and its derivatives in aqueous solutions

Object of investigation - The association phenomenon between cations and аniones dyes in water solutions which contain additives of ionic PAV or organic solvent (acetone). The Research objective - to establish the factors influencing interaction one- or two-charging sulfonephthaleins anions of dyes with cations of cyanines by dyes. Methods of investigation and apparatus - spectrophotometry (spectrophotometr). Theoretical and practical results - the new way of definition of the maintenance of acetone in water is developed. The data about stability and spectral characteristics diverse association can be taken as a principle purposeful search of new systems association dyes. Novelty - spectral, equilibrium and thermodynamic characteristics diverse association one- both two-charging phenolsulfonephtaleins aneones and chains its bromine and alkil derivatives are defined, compared ecsperemently (association constants) and theoretically received (enthalpy formations) characteristics. Introduction degree - it is included in educational process. Field of application - physical chemistry of organic systems.
