Abstract

The present study reports the thermophysical properties such as density and viscosity for aqueous blends of sarcosine (SAR) with 1-(2-aminoethyl) piperazine (APZ) and diethylenetriamine (DETA). The properties have been measured for various mass fractions at atmospheric pressure and temperature ranging from 298.15 to 333.15 K. The analysis of physical property data revealed that both density and viscosity increased with an increase in the mass fraction for both SAR-APZ and SAR-DETA aqueous blends. While these properties showed an opposite behavior with the rise in temperature for both the studied aqueous blends. The experimental density data were used to estimate the isobaric thermal expansion coefficient. A marginal increase and decrease were observed in the estimated isobaric thermal expansion coefficient with an increase in temperature and mass concentration respectively, for both aqueous systems. In addition, empirical correlations such as modified Graber equation and Vogel-Tamman-Fulcher equations were used to correlate the experimental density and viscosity data as a function of temperature and concentration. The correlations were found reliable for the data interpolation.
