“…I NFORMATION concerning the viscosities and densities of vegetable oils and hydrogenated vegetable oils is valuable in the design of processing equipment and in the development of extended applications of these oils in the industry. A systematic study of the variations of viscosity and density with iodine value and temperature, similar to that recently published for cottonseed oils (15), is here reported for peanut oils.…”

“…Using this constant, viscosities can be calculated for any temperature with an accuracy of about 5 percent or better from the viscosity of the oil at a given temperature. A comparison of the density and viscosity characteristics for cottonseed oils (15) and peanut oils shows striking similarities between oils of the same iodine value (Table IV). This agreement is not surprising in view of the known likeness in the composition of these two oils.…”

“…An individual viscometer was used for each oil, the runs being completed in the shortest possible time (about 15 minutes at the high temperatures) that would permit attainment of temperature equilibrium and determination of flow time. As in the investigation on cottonseed oils (15), viscometers were removed from the bath immediately after the determination to minimize possible thermal decomposition and polymerization of the peanut oils at the temperature of the bath.…”

An application of the barcroft-warburg apparatus to the study of antioxidants in fats

Summary The results of the active oxygen method and those obtained with the Barcroft‐Warburg apparatus at 70° C. are in good agreement with storage tests at room temperature on lard to which no anti‐oxidant is added and on lard to which lecithin alone is added. With lard to which d‐isoascorbyl palmitate or d‐isoascorbyl monostearate, in concentrations between 0.01 and 0.10 per cent, is added the results with the Barcroft‐Warburg apparatus are in much better agreement with storage tests than are those of the active oxygen method. The d‐isoascorbyl esters in 0.01 to 0.10 per cent in lard usually behave as antioxidants with the active oxygen method and as pro‐ or antioxidants, depending on their concentration, with the Barcroft‐Warburg apparatus and during storage at room temperature. This study demonstrates that in testing new compounds for antioxidant properties conclusions should not be drawn from results obtained when the experimental conditions of the test are very different from the conditions under which the antioxidant is to be used. It emphasizes the importance of correlating the results of accelerated tests with storage tests.

“…Beyond the measurements made by several authors at one temperature, viscosity data as a function of this variable are due to Macovei, 1 Eryilmaz et al, 2 and Wakeham and Magne. 3 The viscosity data of CSB is scarce from the literature. The few studies over extensive ranges of temperature were made by Eryilmaz et al 2 and Nogueira et al 4 This work aims to provide experimental viscosity data of CSO and CSB at atmospheric pressure and temperatures in the range T = (293 to 373) K and T = (303 to 348) K, respectively.…”

Viscosity of Cottonseed Oil and Biodiesel

et al. 2019

The viscosities of cottonseed oil (CSO) and cottonseed biodiesel (CSB) were measured at atmospheric pressure and temperatures from (293 to 373) K and (303 to 348) K, respectively. The Vogel–Fulcher–Tammann (VFT) and Mauro (MYEGA) equations were selected to represent the temperature dependence of the experimental data, giving deviations within the experimental uncertainties. These equations allowed estimating the glass transition temperatures, which were compared with available values from literature. For viscosity prediction, the group contribution method proposed by Ceriani was compared with the fragment approach given by Zong for CSO. For CSB the Grunberg–Nissan equation coupled with Ceriani and Yuan models was applied, and the influence of the interaction parameter (Gij ) is highlighted.
