Densities, Viscosities, and Speeds of Sound of n-Tetradecane and n-Alkylcyclohexane Binary Mixtures within the Temperature Range (288.15–333.15) K

Abstract: This work reports on the densities, viscosities, and speeds of sound of 2-component mixtures of n-tetradecane and n-alkylcyclohexanes (methyl-, ethyl-, propyl-, butyl-, pentyl, hexyl-, heptyl-, octyl-, decyl-, and dodecylcyclohexane) at select temperatures between 288.15 and 333.15 K and pressure of 0.1 MPa. Decreases in mixture densities, viscosities, and speeds of sound were found with increases in temperature and in the component with the lower property value, except for the speeds of sound of n-butylcycloh… Show more

“…Figure A,B also shows that increasing the alkyl chain length on the n -alkylcyclohexane tends to increase the α E ’s. For equimolar mixtures shown in Figure B, the trend in the data for n -pentadecane is consistent with trends for n -tetradecane and n -tridecane mixed with the same n -alkylcyclohexanes. , There is very little difference in the α E ’s for these three alkanes in mixtures with higher molecular weight n -alkylcyclohexanes.…”

“…The V m E ’s appear to decline linearly with temperature for methyl-, ethyl-, n- propyl-, n- decyl-, and n- dodecyl-cyclohexanes mixtures with coefficients of determination ( R 2 ) for the linear fits generally above 0.98 (Table S5). Linear relationships between V m E and temperature have been reported for ionic liquids and select n -alkylcyclohexanes with n -tridecane and n -tetradecane. , Linear fits for the other n -alkylcyclohexane mixtures compounds had R 2 < 0.98 (Table S5), and second-order fits were better able to capture the trends in the data (Figure ). These results suggest that the packing arrangements of the shorter chain n -alkylcyclohexanes are more affected by temperature than are the longer chain n -alkylcyclohexanes.…”
