ABSTRACT
Viscosities and densities of di-(2-ethylhexyl) phosphoric acid (D2EHPA), kerosene, and their mixtures were determined. The viscosities were incorporated into the Kendal and Monroe equation, which can be used to determine the mixture s viscosity at specific temperatures. The viscosity measurements were made using an Ostwald U-tube viscometer, whereas the density measurements were made by using a hydrometer at temperatures ranging from (303.15 to 343.15) K in 10.00 K increments. The Riedel equation gave an excellent representation of the experimental viscosities of the mixtures as a function of temperature. The Kendal and Monroe equation, using the average molecular weight of the kerosene, gave a good estimation of the mixture viscosities.
