Abstract

In this study, viscosity  and density for two-component mixtures of ethyl Formate and 1-pantanol in a temperature range 293.15K to 323.15K and in different mole fraction measurements. From the data obtained, excess molar volumes was calculated and were correlated by Redlich-Kister type equation as a function of temperature and  mole fraction. Excess molar volume for two-component mixture  of ethyl formate and 1-pantanol in all  range of  temperatures  were measured and whole mole fractions were  positive and increase with increasing temperatures and chain length of 1-Alkanols.
