Water content is one of the most important quality indexes of biodiesel. In this study, the group interaction parameters of UNIFAC model are optimized to improve this model in predicting the solubility of water in fatty acid Me esters and biodiesel. To determine the binary interaction parameters between water and the main functional groups attached to the mols. of the biodiesel compounds, 55 exptl. data points related to the solubility of water in nine pure fatty acid Me esters in the temperature range of 282.2 K-323.2 K are employed. Then, the model is used to predict the water solubility in 10 different biodiesels (60 data points), to evaluate the calculated interaction parameters in predicting the solubility of water in the mixture of fatty acid Me esters. The average absolute relative deviations of the model in predicting the water content of pure fatty acid Me esters and biodiesel are 4.31% and 4.69%, resp. To show the superior performance of the model, the results of the model are compared with the results of previous models. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Application In Synthesis of Methyl heptanoate).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of Methyl heptanoate
