Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Recommanded Product: Methyl nonadecanoate

Insight into the Chemical Complexity of Soluble Portions from Cornstalk Methanolysis was written by Yan, Hong-Lei;Zong, Zhi-Min;Li, Zhan-Ku;Kong, Jiao;Zheng, Quan-Xi;Zhao, Mei-Xia;Li, Yan;Wei, Xian-Yong. And the article was included in Energy & Fuels in 2016.Recommanded Product: Methyl nonadecanoate The following contents are mentioned in the article:

Cornstalk was subjected to methanolysis in the presence of NaOH at 220-320 掳C to afford soluble portions (SPs) 1-5 (SP1-SP5) and an inextractable portion (IEP). The maximum total yield (ca. 51%) of SPs was acquired at 300 掳C with the same mass of NaOH and cornstalk. Under the same conditions, SP1 has the highest yield, followed by SP5 and SP2. The relatively volatile and less polar species in the resulting SPs and IEP were identified with a gas chromatograph/mass spectrometer (GC/MS). The polar species in SP1, SP2, and SP5 were further analyzed with a neg.-ion electrospray ionization Fourier transform ion cyclotron resonance mass spectrometer (FTICRMS). The anal. with GC/MS shows that phenolic compounds and alcs. are the dominant group components in SP1 and SP2, resp., while the predominant compounds in esterified SP3-SP5 and IEP are esters. According to anal. with FTICRMS, thousands of compounds were detected in SP1, SP2, and SP5. Most of the compounds are On (n = 1-10) class species with double bond equivalent (DBE) values of 1-14 and carbon atom numbers of 5-35. The most abundant class species in SP1, SP2, and SP5 are O3, O3, and O8, resp. SP1 and SP2are rich in O2-O4 class species with DBE values of 5-8, which may be attributed to lignin-derived compounds Different from SP1 and SP2, SP5 has relatively high contents of O5-O10 class species, corresponding to various acidic species. In addition, N1On (n = 0-8) class species with DBE values of 3-14 were also identified, which should contain a pyrrole ring as the parent structure. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Recommanded Product: Methyl nonadecanoate).
