Lab Report Synthesis of Methyl Stearate

Synthesis of methyl group radical radical radical thoroughgoing radical Stearate Post-Lab Submitted by Matthew Sharma TA: Evan Determining the moderate Reagent methyl radical Oleate (MW= 296.49 g/mol) Amount utilise = 1.141g (1.141g)(1mol / 296.49g) = 0.003848 mol ? The limiting reagent for the chemical reception is methyl oleate because hydrogen is utilize in excess Theoretical Yield methyl Stearate (0.003848 mol)(298.504g/mol outpution) = 1.1486 g methyl stearate Percent Yield Given the 1:1 stoichiometry of the reaction: light speed% 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 concoction and then filtrated and recrystallized to purify the methyl stearate product. The percent yield of the black-and-blue crystal product may have been low delinquent to incomplete hydrogenation of the methyl oleate, mystic in thought(p) product in the filtration/ recrystallization process, and incomplete transfer between the centrifuge tube to a beaker. The nuclear magnetic sonority 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 given up to the highly negatively charged type O atom. The CH3 hydrogen atoms observe no splitting because they have no neighbor protons (N=0) therefore it is a singlet. The leash peaks at around 0.90 ppm bring the CH3 group on the opposite end of the molecule, because the triad hydrogen atoms (HB) are uttermost(a) from the electronegative oxygen atoms and because the protons have both neighboring protons (N=2) indicating a triad. 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 2 neighboring protons (N=2) indicating a triplet and it is next to the electronegative threefold bond. The NMR spectrum does...If you want to become a full essay, methodicalness it on our website: Ordercustompaper.com
