Abstract
The densities and the refractive indices of seven samples of neutralized, hydrogenated palm olein and six fractions from palm oil were determined. It was found that both the density and the refractive index decreased linearly with increasing temperature over the range 30C to 80C. The temperature coefficients for these propierties were determined for both groups of samples. These propierties were also found to be linearly dependent on the iodine values. Equations were developed for the two propierties for each group of samples. These equations aaccurately predict the densities and the refractive indices for all the samples at the temperatures studied.The densities and the refractive indices of seven samples of neutralized, hydrogenated palm olein and six fractions from palm oil were determined.
