Herein, catalytic impact of aqueous-micellar solution of twin headed 16-s-16 (s = spacer) gemini surfactants (GS) was measured in the study of ninhydrin (nin) with aspartic (Asp) amino acid. The study was performed over the different range of reactants’ concentration, temperature and pH. Reaction obeyed the order to be resp. fractional and unity in [nin] and [Asp]. The values of several quantities, viz., critical micellar concentration (cmc), thermodn. parameters, and binding parameters were calculated and described herewith. The exptl. outcomes depict that the reaction is catalyzed, significantly, by twin headed gemini surfactants and follow the order at all concentration as: GS-4 > GS-5 > GS-6. In the rate constant (kψ) vs. [GS] rate profiles, kψ intensifies even at below cmc values of surfactants (region I), and previously observe practically unchanged behavior (region II). Finally, a fast changes in kψ is detected (region III). Catalytic impact of twin headed GS achieved in this study is deduced by using a model called as micellar pseudo-phase in which rate constant depends on both the reactants. The numerous kinetic constants in twin headed geminis were evaluated and elaborated. An acceptable mechanism reliable with kinetics comprising the development of Ruhemanns’ purple between nin and Asp has been proposed. The experimental part of the paper was very detailed, including the reaction process of 1,6-Dibromohexane(cas: 629-03-8SDS of cas: 629-03-8)
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of pyrrolo-tetrathiafulvalene molecular bridge (6PTTF6) to study redox switching behavior of single molecules; synthesis of water-soluble thermoresponsive polylactides.SDS of cas: 629-03-8
