Methyl nonadecanoate (cas: 1731-94-8) 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.Electric Literature of C20H40O2

To develop a method for direct transesterification of wet yeast using immobilized lipase, the oleaginous yeast Saitozyma podzolica Zwy-2-3 and the lipase producing Burkholderia pyrrolica WZ10-3 were used as materials for production of biodiesel. Fe3O4@SiO2-CHO prepared by modifying Fe3O4 with TEOS, APTES and glutaraldehyde. The biocatalysts covalently cross-linked with WZ10-3 lipase by Fe3O4@SiO2-CHO were characterized by FTIR, XRD and TEM. When the enzyme dosage, glutaraldehyde concentration, temperature and time were 30.22 mL, 2.0%, 40°C and 4 h, the immobilized lipase activity and immobilization rate reached 10038.0 U/g and 96.9%, resp. The optimum temperatures for immobilized and free lipase were 60 degrees and 40 degrees. The immobilized enzyme still had 80% enzymic activity after 48 d storage at 4°C. The optimized conditions for the direct conversion of immobilized lipase to esterified wet yeast (one-step) were: enzyme dosage 2.5 g, reaction temperature 35°C; water content 15%; and molar ratio of n-hexane to methanol 3: 1. The transesterification rates of one-step method for oil and biomass were 98.12% and 56.11%, resp. In contrast, the two-step method was only 88.75% and 51.21%. The immobilized enzyme had 90% enzyme activity after 10 times of reuse. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Electric Literature of C20H40O2).
