Nutmeg’s triglycerides are mainly the glycerol ester of a single fatty acid which is called myristic acid. This ester, called trimyristin, represents the 20-25% dried weight of nutmeg (Wilcox amp; Wilcox, 120). The purpose of this lab is to isolate trimyristin from nutmeg by performing a simple solid-liquid extraction and to purify the trymyristin using the method of recrystallization. Procedure: Place 5 g of nutmeg and 50 mL of DCM into a 100 mL round bottom flask, and reflux the mixture for 30 minutes. Refer to p.120 (E) in Wilcox amp; Wilcox. Rotary evaporation will be used instead of steam distillation. Data: Mass of Nutmeg | 5.0127g | Mass of Crude Trimyristin | 2.3516 g | % Yield of Crude | 46.91 % | Mass of Pure Trimyristin | 0.3352 g | % Recovery from Recrystallization | 6.69% | Overall % Yield from Nutmeg | 10.5%(pure); 45.6%(crude+pure) | Results/Discussion: The percent recovery from recystallization and the overall percent yield from nutmeg are extremely low due to the loss of trimyristin from filtration and the round bottom flask. The literature IR and the experiment IR are very similar, containing many of the same peaks; therefore, the purification of trimyristin was done successfully with a smaller than expectedShow MoreRelatedUsing The Solid Liquid And Liquid Extraction Techniques For Extract A Strong Acid1613 Words   |  7 Pageswhen using the solid-liquid and liquid-liquid extraction techniques to extract a strong acid, weak acid, base, and neutral compound from a mixture. During the solid-liquid section of the experiment, 0.5 M NaHCO , 0.5 M NaOH, 0.5 M HCl, and distilled water are used to dissolve and separate the acid, phenol, and amine solutions from the mixture, leaving the neutral compound remaining. After adding 3 M HCl to the acid and phenol solutions and3 M NaOH to the amine solution, the solutions and solids formedRead MoreIdentifying An Unknown Solid Using Melting Point1589 Words   |  7 Pagesinserted a capillary tube containing approximately 2 to 3 mm of benzoic acid into a manual Mel-Temp melting point apparatus. With the Mel-Temp dial set between 3 and 4, the temperature increased at a steady rate of approximately 2 ° C per minute from a plateau set at 90 ° C. The first appearance of liquid occurred at 119 ° C, and the benzoic acid completely melted by 122 ° C giving a melting point range of 119 ° C to 122 ° C for benzoic acid. Repeating the procedure for 2-naphthol returned a melting pointRead MoreRecrystallization And Identification Of Unknown1796 Words   |  8 Pagesthen identify it through measuring the melting point. Introduction The main goal of this laboratory project was for an impure compound to be purified through recrystallization, which entails clearing impurities from the compound, and allows the separation of the pure product, which forms orange hexagonal crystals. The crystals will have impurities attached to them initially during formation, but over time compounds will have all the impurities removed as long as recrystallization is not too fast
