“…Among the latter, the next have been regarded: Fischer's F value (F), residual mean squared error (RMSE), variation explained (VE) [48] and Akaike information criterion (AIC) [49]. These statistical parameters and criteria are defined in detail elsewhere [50] and in the Supplementary material. They have previously been used successfully for kinetic modelling discrimination purposes [51].…”

“…When GC generates together with methanol, in the former case, and ethylene glycol, in the latter, the system becomes entirely miscible with a transition from a biphasic liquid-liquid system to a single-phase liquid taking place [43,44]. In turn, this feature has proven of importance when determining a kinetic model for reaction {a} using K 2 CO 3 as catalyst [28].…”

“…However, the most followed synthetic path is the reaction of glycerol with organic carbonates to yield alcohols or glycols together with GC. When glycerol reacts with DMC, two molecules of methanol (MeOH) are produced [26][27][28], whereas a molecule of ethylene glycol (EG) forms from the reaction with ethylene carbonate (EC) [29], as represented in Fig. 1.…”

Fatty acids have a great importance in several industrial activities like the manufacture of ingredients for foods, paints, soap, detergents and a wide array of other products in the fast moving consumer goods industry. Processing of fatty acids requires a good knowledge of transport properties, such as viscosity. This work presents a compilation of experimental values of the viscosity of three long‐chain saturated fatty acids, namely: myristic, palmitic and stearic acid. First, a study of the dependence of the viscosity of these fatty acids with temperature is presented comparing results with previously existing data in literature and validating data and models statistically. Then, a thorough analysis of the viscosity of binary mixtures of the aforementioned fatty acids was conducted. To do so, such property was measured over the entire range of compositions in increments of the molar fraction of the components of 0.1 at temperatures ranging from above the melting points of the fatty acids to 373.15 K and correlation with respect to composition and temperature with the Jouyban–Acree model. Last, the so‐called viscosity deviations were computed and correlated with Redlich–Kister equations to explain the variation as a function of the molar composition of the corresponding mixture. Discrimination of different models to correlate the experimental data was made on the basis of different statistical criteria. Practical Application: Good knowledge of transport properties such as viscosity is important to understand the physics and processing of materials. Contrary to simply using a viscometer, here cone and plate rheometry is used to accurately determine the viscosity of myristic, palmitic and stearic acids and their binary mixtures, which have high melting points compared to other liquids. In addition, the presentation of statistical discrimination tools like information criteria is highly relevant to understand the goodness of fit of models and the selection of the most statistically relevant equations without using more parameters than strictly necessary. The viscosities of pure myristic, palmitic and stearic acids as well as their binary mixtures are determined and a discrimination of models is performed to understand the most appropriate number of parameters to describe the behaviour.
