The Effect of Temperature Variation on Studies of Coconut and Palmoline Oils

C. Sivaram and A. Shiva Naga Dakshina Murthy

The effect of temperature on density of coconut and palmoline oils was observed at various temperatures using DMA48 (ADPAAR – made in Austria) density meter. The density linearly decreases with increase in temperature. The change in density per K, is in good agreement with Paquot observation, for these oils. The modified Rackett equation can be successfully employed to estimate the densities as a function of temperature of vegetable oils, if various fatty acid compositions of a particular oil and their critical constants are known.
