Estimation of boiling points by investigations of viscosity Arrhenius behaviours in Methyl Benzoate + n-Hexane binary liquid systems at atmospheric pressure

On the Homographic Dependence of Activation Energy and Viscosity Arrhenius' Temperature for Some Pure Fluids

“…Arrhenius and temperature parameters: A sample of 101 experimental data provided from the literature on viscosity of pure Newtonian fluids (Table-1) studied at different temperature ranges and at atmospheric pressure is used in this work in order to analyze the existence of any eventual causal correlation between the Arrhenius type-equation, as knowing the activation energy (Ea) and the entropic factor (ln As) and eventually the melting temperature (Tm) and boiling temperature (Tb). Also, the present investigation includes additional parameters such as the Arrhenius activation temperature (T * = Ea/R) and the Arrhenius temperature (TA = -Ea/R.ln As) as defined in previous works [1][2][3][4][5][6][7][8][9][10][11].…”

“…So, in the light of these observations and especially the probable existence of vertical and horizontal asymptotes in Fig. 2d, we tested a suggested homographic dependence linking Y = E a with X = (1/T A ) expressed as follows: To consider about the dependence of the viscosity with some physico-chemical properties, we have tested the boiling temperature (Tb) which is already predicted through the temperature-dependence presented in previous works [1][2][3][4][5][6][7][8][9][10][11]. For that, in order to measure up and assess eventual relationship between the target parameters, we have carried out the Spearman's rank correlations tests [53], where the null hypothesis assumes the independence of the variables.…”

“…The present result allows as expecting a very predictive quality of approximation during their practical application. Finally, regarding the new concept of boiling temperature prediction through the temperature-dependence of dynamic found in previous works [1][2][3][4][5][6][7][8][9][10][11] and the mutual correlation between the two Arrhenius parameters (Ea) and (ln As) presented in earlier works [55,56], a 3D global view ( Fig. 5) of graphical correlations between Arrhenius parameters and the boiling temperature of the set of studied classical solvents well confirms the investigated causal correlation presented in the present and previous works.…”

“…Recently we have initiated a collaborating research axis on application of thermodynamic/transport properties of some engineering fluid systems in suggested correlation equations [1][2][3][4][5][6][7][8][9][10][11]. Considering the experimental values in the literature, here it is extended to investigate the viscosity Arrhenius behaviour along with a new parameter applied as Arrhenius temperature (TA), in some classical fluids at different temperatures.…”

“…In this framework, new correlation will be developed for the nanofluids attributes in terms of particles volumetric concentration and absolute temperature measurements. We can add that, due to the cohesive forces, the causal correlation between the Arrhenius parameters and the absolute temperature through the temperature of vaporization is highly affected by the surface tension, enthalpy of vaporization, and the friccohesity [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”
