Sci., 2013, vol. Stability and catalytic activity of commercial CaO were significantly improved after modifying calcium oxide with bromobenzene in a simple way. 183, p. 454. How do I calculate the limiting reagent and percent yield for creating tetraphenylcyclopentadienone in the lab from by aldol condensation. 67, p. 5289.
I, think there were a few reasons I got the results that I did. If requested by your instructor, obtain an IR using the Nujol mull technique and identify pertinent peaks. The Buchner filtration is where I typically, lose most of my product, so I should be more careful while performing it and ensure most, of the product is not lost around the edges of the filter paper. Tang, Y., Chen, G., and Lu, Y., Res. Aldol condensations are important in organic synthesis, because they provide a good way to form carbon–carbon bonds. https://doi.org/10.1134/S0023158416040145.
loss was not being able to scrape all of the product off of the filter paper after it had dried. Sources, 2008, vol. Tang, Y., Xu, J.F., and Gu, X.F., J. Chem.

It is calculated to be the experimental yield divided by theoretical yield multiplied by 100%.
A: Chem., 2001, vol. It was created by reacting benzil with dibenzyl ketone. If the actual and theoretical yield are the same, the percent yield is 100%. Xie, Y.W., Sharma, K.K., Anan, A., Wang, G., Biradar, A.V., and Asefa, T., J. 71, p. 5440. Hattori, H., Chem. Aldol Condensation A. It's possible for percent yield to be over 100%, which means more sample was recovered from a reaction than predicted. CAS For this experiment we obtained 0.1963 g of product. Stability and catalytic activity of commercial CaO were significantly improved after modifying calcium oxide with bromobenzene in a simple way. Kinet Catal 57, 439–445 (2016). volume 57, pages439–445(2016)Cite this article. First, my product looked visibly different from most other students. High efficient Aldol condensation reaction utilizing modified calcium oxide as stable solid base catalyst. In this equation, the reactant and the product have a 1:1 mole ratio, so if you know the amount of reactant, you know the theoretical yield is the same value in moles (not grams!). Article percent yield = (actual yield/theoretical yield) x 100%. Podrebarac, G.G., Ng, F.T.T., and Rempel, G.L., Chem. One last potential source of. Serra-Holm, V., Salmi, T., Multamäki, J., Reinik, J., Mäki-Arvela, P., Sjöholm, R., and Lindfors, L.P., Appl.
It's possible for percent yield to be over 100%, which means more sample was recovered from a reaction than predicted. Google Scholar.
