Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. 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.Computed Properties of C20H40O2

Synthesis and characterization of Ca/SBA-15 solid base catalyst and its application in biodiesel production via waste cooking oil was written by Hou, Qian-fen;Zhang, Qian-qian;Guo, Hua-rong;Li, Ling. And the article was included in Huaxue Yu Shengwu Gongcheng in 2015.Computed Properties of C20H40O2 The following contents are mentioned in the article:

Ca/SBA-15 Solid base catalyst was prepared by sol-gel method, using tetra-Et orthosilicate as silicon source, calcium acetate as calcium source and P123 as template agent. The related physicochem. properties of the catalyst were characterized by XRD, FTIR, TEM and N2 adsorption-desorption isotherms. Then it was used in the transesterification reaction of waste cooking oil and methanol to produce biodiesel. Results showed that, catalyst 0.2Ca/SBA-15-700 with Ca/Si molar ratio of 0.2, calcined at 700°C exhibited the best catalytic activity, which could well maintain the original two-dimensional hexagonal order mesoporous structure and had a BET sp. surface area of 406.7 m2·g-1. The yield of biodiesel could reach 94.7% under the optimum conditions of methanol/oil molar ratio of 12, catalyst dosage of 5%, reaction temperature of 65°C and reaction time of 7 h in N2 atmosphere. After being washed and dried, the catalyst could be directly reutilized in the next circle without reactivation. After the fifth circle, the catalytic activity decreased but the yield of biodiesel was still above 86%. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Computed Properties of C20H40O2).
