Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Experimental and correlational study of isobaric molar heat capacities of fatty acid esters: Ethyl nonanoate and ethyl dodecanoate was written by Liu, Xiangyang;Zhu, Chenyang;Yang, Feng;Su, Chao;He, Maogang. And the article was included in Fluid Phase Equilibria in 2019.Electric Literature of C20H40O2 The following contents are mentioned in the article:

An exptl. study on the isobaric molar heat capacities of Et nonanoate and Et dodecanoate was performed at temperatures between 303 K and 393 K and at pressures between 0.1 MPa and 25.2 MPa. An increase of isobaric molar heat capacity with temperature increase was observed, and temperature was found to have a greater effect on isobaric molar heat capacity than pressure. Then the isobaric molar heat capacity data of 18 saturated fatty acid Me and Et esters in literature were selected, to get a general correlation for the isobaric molar heat capacity of saturated fatty acid alkyl esters. The average absolute relative deviation and the maximum deviation of the present correlation from exptl. data are lower than 0.70% and 3.82%, resp. At last, to test the predictive ability of the proposed correlation, the heat capacities of Et nonanoate and Et dodecanoate were calculated The average absolute relative deviation and the maximum deviation from our exptl. results are 0.88% and 2.10%, resp. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Electric Literature of C20H40O2).
