Lab Report Synthesis of Methyl Stearate

Synthesis of methyl radical radical Stearate Post-Lab Submitted by Matthew Sharma TA: Evan Determining the moderate Reagent methyl group Oleate (MW= 296.49 g/mol) Amount utilize = 1.141g (1.141g)(1mol / 296.49g) = 0.003848 mol ? The limiting reagent for the chemical reaction is methyl oleate because enthalpy is used in excess Theoretical Yield Methyl Stearate (0.003848 mol)(298.504g/mol mathematical production) = 1.1486 g methyl stearate Percent Yield aband aced the 1:1 stoichiometry of the reaction: 100% x (0.2551g product / 1.1486g abstractive yield) = 22.2% Conclusion A 22.2% yield of synthesized methyl stearate was obtained via the catalytic hydrogenation of methyl oleate in the presence of the catalyst 10% palladium on carbon. The product was centrifugated to remove the catalyst from the mixture and thence filtrated and re crystallized to purify the methyl stearate product. The percent yield of the white crystal produc t whitethorn have been low due to unelaborated hydrogenation of the methyl oleate, deep in thought(p) product in the filtration/ recrystallization process, and broken transfer between the centrifuge tube to a beaker. The nuclear magnetic resonance spectrum of the purified product suggests that its identity is methyl stearate. The one peak at 3.

482 ppm indicates the OCH3 group, because the hydrogen atoms (HA) are attached to the highly electronegative group O atom. The CH3 hydrogen atoms observe no carve up because they have no neighbor protons (N=0) therefore it is a singlet. The third peaks at around 0.90 ppm represent the CH3 group on the opposit! e end of the molecule, because the three hydrogen atoms (HB) are uttermost(a) from the electronegative oxygen atoms and because the protons have two neighboring protons (N=2) indicating a triplet. The three peaks at around 2.40 ppm represent the CH3 group neighboring(a) to the C=O bond, because the hydrogen atoms (HC) have two neighboring protons (N=2) indicating a triplet and it is abutting to the electronegative double bond. The NMR spectrum does...If you want to get a full essay, order it on our website: OrderCustomPaper.com
