Intro: In this experiment, soap was obtained from nutmeg through a series of reactions. First, trimyristin (triglyceride) was obtained from nutmeg through extraction with boiling ether. Next, basic hydrolysis (saponification) was performed on trimyristin to obtain sodium myristate (first, the trimyristin was heated under reflux with NaOH and 10% ethanol; then after being cooled, water and saturated NaCl were added and the soap was filtered). Sodium myristate was acidified using HCl and filtered to produce myristic acid Results and Discussion: The starting masses and final masses of all products were measured and recorded. The melting point values of the products were determined and recorded. The percent recovery for the isolation of sodium myristate was calculated, as was the percent yield of the reaction (Table 1). TLC plates were spotted and developed in iodine vapors for trimyristin and myristic acid. The Rf values were calculated and tabulated (Table 2) and the TLC plates were diagramed (TLC Plate Diagrams). The sodium myristate was tested by taking three 5 mL samples (from sodium myristate, 0.5 g,
