Methyl heptanoate (cas: 106-73-0) 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.Application of 106-73-0

Castor oil has been widely used as raw material to obtain compounds such as paints, solvents, rubbers, polyurethane polymers and chem. inputs. Then, one highlighted route is thermal cracking of castor oil to produce bio-oil, mainly composed of heptaldehyde and Me undecenoate, which are used as precursors of lactones in the food and beverage industry. The main aim of this study was to evaluate the separation heptaldehyde and Me undecenoate by distillation of bio-oil from thermal cracking of the Me esters in castor oil (MECO). Distilled fractions were analyzed by gas chromatog. (GC). Thus, it was possible to concentrate the fractions of heptaldehyde and Me undecenoate in a section with a distillation system at atm. pressure with a distillation rate of 5.0 mL min-1 at 270°C, which motivates new researches for up-scaling of the process. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Application of 106-73-0).
