Phaleria macrocarpa (Mahkota dewa) seed was examined to determine the optimal conditions of oil yield by solvent extraction method using n-hexane as extracting solvent. Response surface methodol. (RSM) was employed to describe explicitly the influence of extraction time, temperature and solvent-to-feed ratio on the yield of oil using central composite design (CCD). The linear, quadratic and interaction terms of the studied variables have significant (P < 0.05) effect on the oil yield. The temperature of 72 °C, extraction time of 8.4 h and solvent-to-feed ratio of 10.9 mL/g were the optimal conditions for seed oil extraction The maximum oil yield was 55.32 g/100 g dry weight under these optimal conditions. Main chem. constituents of oil were determined by Gas chromatog.-mass spectroscopy (GC-MS) and Fourier transform IR spectroscopy (FTIR). Twelve components were identified by GC-MS anal. after formation of fatty acid Me ester (FAME). Total saturated fatty acids were 19.38% whereas monounsaturated fatty acids and polyunsaturated fatty acids were 44.23% and 36.38%, resp. Oleic acid, 18:1 (43.56%) and linoleic acid, 18:2 (36.25%) were the main fatty acid constituents of Mahkota dewa seed oil. The quantity of unsaturated fatty acids was higher than saturated fatty acids in P. macrocarpa seed oil. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Application In Synthesis of Methyl nonadecanoate).
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. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Methyl nonadecanoate
