Catalytic role of 16‐s‐16 micelles on condensation reaction of ninhydrin and metal‐dipeptide complex

Abstract: Catalytic role of 16-s-16 (s = spacer) micelles on condensation reaction of ninhydrin and metal-dipeptide ([Cu (II)-Gly-Leu] + ) complex have been studied by varying reactants concentration at various temperatures ranges from 333 K to 353 K. The reaction was monitored at definite time interval with the help of UV-vis spectrophotometer. For evaluation of critical micelle concentration (cmc) of 16-s-16 surfactants with and without reactants (ninhydrin and metal-dipeptide complex), conductometic technique was use… Show more

“…As the color of product disappears, several modifications, which include change of different solvents, pretreatment of enzymes, and addition of several surfactants, were made toward the stability of product. [6][7][8][9][10][11][12][13] In our present case, coordination of zinc metal ion was explored on the reaction to stabilize the product and color yield was indeed affected.…”

“…The organic compounds having both polar and apolar parts in the structure of the same molecule are known as surfactants that show unique solubility property as well as aggregation behavior in aqueous medium . This aggregated form of surfactant (micelle) occurred due to the balance of hydrophilic and hydrophobic interaction beyond their particular concentration which is termed as critical micelle concentration ( cmc ) and any concentration inferior to cmc , surfactant exists in monomeric form . The extent of interaction of the surfactant molecules is a function of the microenvironment.…”

“…[1] This aggregated form of surfactant (micelle) occurred due to the balance of hydrophilic and hydrophobic interaction beyond their particular concentration which is termed as critical micelle concentration (cmc) and any concentration inferior to cmc, surfactant exists in monomeric form. [2,3] The extent of interaction of the surfactant molecules is a function of the microenvironment. Thus, any change of microenvironment of a surfactant for example presence of additives, addition of second surfactant, and temperature is the cause of modified hydrophilic and hydrophobic interaction and results in changing different physicochemical properties, eg, cmc, extent of degree of dissociation as well as thermodynamic parameter.…”

“…Alkanediyl-α,ω-bis-type gemini surfactants have two head groups and hydrocarbon tails joined through a spacer near or close to head groups (Menger and Keiper, 2000;Zhou et al, 2017). Compared to the traditional monomeric surfactants, geminis show advanced properties due to introduction of spacers, such as low cmc, emulsification, unfamiliar aggregation behavior, and high surface activity (Akram et al, 2014b;Kumar and Rub, 2019a;Rosen and Tracy, 1998;Wang et al, 2013;Zana, 2002a). Because of their unique properties preferred over conventional surfactants, they are used in most practical applications including pharmaceutical, detergency, and other commercial purposes.…”
