In this work a comparative study is carried out of the critical properties of temperature and pressure applied for the palmitic, stearic and oleic fatty acids, provided by different bibliographical sources. These properties are used in the Rackett's equation to estimate the density of the pure substances. The most commonly employed methods are described and applied in these cases to estimate these critical properties. A group of values of critical properties is selected to estimate the density using the Rackett's equation. The values of the critical properties that give a better estimation of the density, according to Rackett's equation, when compared with the experimental results are proposed. It is demonstrated that the selection of the critical properties influences in a decisive way in the estimation of physical properties by means of the Rackett's equation.
