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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C20H40O2

A comparison study of extraction methods for bio-liquid via hydrothermal carbonization of food waste was written by Bang, YeJin;Choi, Minseon;Bae, Sunyoung. And the article was included in Analytical Science & Technology in 2018.Formula: C20H40O2 The following contents are mentioned in the article:

The hydrothermal carbonization method has received great attention because of the conversion process from biomass. The reaction produces various products in hydrochar, bio-liquid, and gas. Even though its yield cannot be ignored in amount, it is difficult to find research papers on bio-liquid generated from the hydrothermal carbonization reaction of biomass. In particular, the heterogeneity of feedstock composition may make the characterization of bio-liquid different and difficult. In this study, bio-liquid from the hydrothermal carbonization reaction of food wastes at 230 °C for 4 h was investigated. Among various products, fatty acid Me esters were analyzed using two different extraction methods: liquid-liquid extraction and column chromatog. Different elutions with various solvents enabled us to categorize the various components. The eluents and fractions obtained from two different extraction methods were analyzed by gas chromatog. with a mass spectrometer (GC/MS). The composition of the bio-liquid in each fraction was characterized, and seven fatty acid Me esters were identified using the library installed in GC/MS device. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Formula: C20H40O2).
