One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, 122-18-9, such as the rate of change in the concentration of reactants or products with time.In a article, authors is Molla, Mohammad Robel, mentioned the application of 122-18-9, Name is N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride, molecular formula is C25H46ClN
Interaction between tetradecyltrimethylammonium bromide and benzyldimethylhexadecylammonium chloride in aqueous/urea solution at various temperatures: An experimental and theoretical investigation
The mixed micelle formation between tetradecyltrimethylammonium bromide (TTAB) and benzyldimethylhexadecylammonium chloride (BDHAC) has been investigated in the absence as well as attendance of urea using conductivity technique. The evaluated values were examined in accordance with Rubingh model. The obtained values of critical micelle concentration (cmc) were smaller than cmcid values suggesting attractive interactions between the constituents of solution. The micellar mole fractions (X1Rub) of BDHAC, estimated by Rubingh model, were always higher than their ideal values (X1id) suggesting the high contributions of BDHAC in mixtures of TTAB and BDHAC. Interaction parameter (beta) value was found to be negative showing an attractive interaction between the studied components. Activity coefficients (f1Rub and f2Rub) were always smaller than one in all cases and it indicates the attractive interaction between TTAB and BDHAC. The values of DeltaGmo are found to be negative in all the cases which indicate the spontaneous formation of micelle. The values of DeltaH0m are negative in all cases indicating the exothermic process. The values of DeltaS0m are positive in case of aqueous medium and 500?mmol¡¤kg??1 urea solutions but found to be negative in attendance of 1000?mmol¡¤kg??1 urea. The values of excess free energy of micellization (DeltaGexRub) were also estimated and achieved to be negative showing the stability of mixed micelles.
