We obtained crystals that cis-norbornene-5 6-endo-dicarboxylic anhydride melting point a small and more powdery than plate-like. Even though our crystals did not turn out as we had hoped, the melting point range for our crystals was very close to the literature value. The calculations for the percent yield are as follows: First, the moles of the reactants must be calculated: Through these calculations we can see that the cyclopentadiene is the limiting reagent is the cyclopentadiene because the reaction between cyclopentadiene and maleic anhydride is a reaction. We were only able to produce a yield of A yield this low was not expected, but was enough to measure the melting point to see if we had indeed produced cis-Norbornene-5, 6-endo-dicarboxylic anhydride. As cyclopentadiene is left out over a period of a few days, the molecules slowly dimerize and thus become dicyclopentadiene.

Dicyclopentadiene would not result in the desired product, cis-Norbornene-5, 6-endo-dicarboxylic anhydride, so this must be remedied. In order to un- dimerize dicyclopentadiene, it must be heated to just under its boiling point to make fresh cyclopentadiene.

With our melting point being so close to the literature value for cis-Norbornene-5, 6-endo-dicarboxylic anhydride, it is very likely that the desired product was obtained. This reaction does not seem to be very efficient at all. By using 0. Conclusion: The Diels- Alder reaction is one of the most important types of reactions in organic chemistry Weldegirma, This reaction is so important because of its ability to form new carbon-carbon bonds. Diels- Alder reactions are used constantly in the medical field due to its diverse uses. It has been in studies of ribozymes and creating ribozymes synthetically Cons of democracy, I believe that we did accomplish what we set out to do in this lab.

Rotrude of trier Melting point of cis-norbornene-5 6-endo-dicarboxylic anhydride Challenges in the global business environment Melting point of cis-norbornene-5 6-endo-dicarboxylic anhydride Video Inducing crystal formation Production[ edit ] Maleic anhydride is produced by vapor-phase oxidation of n-butane. The overall process converts the methyl groups to carboxylate and dehydrogenates the backbone. The selectivity of the process reflects the robustness of maleic anhydride, with its conjugated double-bond system. Navigation menu Traditionally maleic anhydride was produced by the oxidation of benzene or other aromatic compounds. As ofonly a few smaller plants continue to use benzene.
