An orthogonal array design was employed to optimize the subcritical fluid extraction of seed oil from tree peony (Paeonia suffruticosa Andr.). The fatty acid composition and physicochem. properties of the seed oil were analyzed. The results showed that the optimum extraction conditions were determined to be extraction at 50°C and 0.5 MPa performed three times for 30 min each, resulting in an oil yield of 24.16%. Twelve fatty acids were identified in the extracted seed oil and the major fatty acids were linolenic acid (45.4122%), linoleic acid (38.1199%), palmitic acid (11.1246%) and stearic acid (3.6489%). The physicochem. indexes were as follows: relative d. 0.9013, index of refraction 1.4742, acid value 3.25 mg/g, iodine value 175 g/100 g, saponification value 176 mg/g, and peroxide value 1.48 meq/kg. 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. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application In Synthesis of Methyl nonadecanoate
