This work deals with the modeling of dynamic viscosities of several fatty acid esters (FAEs) and biodiesels based on the friction theory (FT) along with a perturbed hard-dimer-chain equation of state (PHDC EOS). The model used three mol. parameters (ε, σ, m) and liquid d. as well, all of which were estimated from the PHDC EOS. The PHDC EOS could predict the d. and isothermal compressibility coefficients in 278.15-393.15 K range and pressures up to 210 MPa with the average absolute relative deviations (AARDs) of 0.52% and 4.77%, resp. Then, the proposed FT-based model has been employed for predicting the dynamic viscosities of several FAEs and biodiesels in 293.15-393.15 K and pressures up to 200 MPa. The model predicted 892 exptl. data points for dynamic viscosities of 10 FAEs and 3 biodiesels with the AARD of 1.70%. Further, the degree of accuracy of proposed model has also been compared with some semi-theor. and empirical approaches. Our comparison results revealed the superiority of the proposed model against the literature approaches. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Product Details of 106-73-0).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Product Details of 106-73-0
