Density estimation for fatty acids and vegetable oils based on their fatty acid composition
TLDR
The liquid density of vegetable oils can be estimated by using mixture properties corresponding to the fatty acid composition and a correction for the triglyceride form as discussed by the authors, which is explicitly temperature-dependent.Abstract:
The liquid density of fatty acids can be accurately estimated by the modified Rackett equation over a wide range of temperatures. The modified Rackett equation requires the critical properties and an empirical parameter,Z

, for each acid as the basis for computing density as a function of temperature. The liquid density of vegetable oils can be estimated by using mixture properties corresponding to the fatty acid composition and a correction for the triglyceride form. The density prediction is explicitly temperature-dependent.read more

Physical properties of liquid edible oils
TL;DR: In this article, literature values of density, viscosity, adiabatic expansion coefficient, thermal conductivity, specific heat (constant pressure), ultrasonic velocity, and ultrasonic attenuation coefficient are compiled for a range of food oils and water at 20°C, and a series of empirical equations are suggested to calculate the temperature dependency of these parameters.

Density and viscosity of vegetable oils
TL;DR: In this paper, a generalized method was developed to estimate the liquid density of vegetable oils and fatty acids, which was based on fatty acid critical properties and composition of the oil, and the correlation for vegetable oils was calculated based on the ratio of fat acid critical and vegetable oil critical properties.
