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 30°C to 80°C. The temperature coefficients for these properties were determined for both groups of samples. These properties were also found to be linearly dependent on iodine values. Equations were developed for the two properties for each group of samples. These equations accurately predict the densities and the refractive indices for all the samples at the temperatures studied.
