Abstract

The physical properties (viscosity, surface tension and density) were computed in laboratory using different laboratory equipment for binary and pure system at (P=1 atm and T=25C). At mole fraction 0.5, the excess volume was found to be positive value while the deviation in viscosity and surface tension was found as negative values at the same mole fraction. Experimental excess properties were compared using Redlich-Kister equation and showed acceptable standard deviation. The inter molecular interaction of the 1-Butanol and Ethyl acetate found to be negligible and the vulnerability of the hydrogen bonds according to the FTIR spectra to a mixture of 1-Butanol and Ethyl acetate is consistent with the positive values of excess volume. Overlying the values of surface tension and the deviation in viscosity was found as negative values for all mole fractions studied.
