aldol condensation low percent yield
Correspondence to Power. 5, p. 145. Aldol condensation of acetophenone and benzaldehyde, as well as various benzaldehydes was carried out efficiently to produce chalcone with a good selectivity and high yields by using modified CaO as a solid base catalyst. Usually, percent yield is lower than 100% because the actual yield is often less than the theoretical value. - This equates to a 78% yield of product. Ebitani, K., Motokura, K., Mori, K., Mizugaki, T., and Kaneda, K., J. Org. Eng. The humidity test over modified CaO reveals that the basic sites of modified CaO are resistant to CO2 and moisture. Stability and catalytic activity of commercial CaO were significantly improved after modifying calcium oxide with bromobenzene in a simple way. Catal. Aldol Condensation A. One last potential source of. This is a poor yield as Dr. Fjetland, explained that the yield is typically higher for this reaction than most other reactions. Rev., 1995, vol. A: Chem., 2005, vol. Aldol Condensation Report.docx - Aldol Condensation A Percent Yield The percent yield for my aldol product was 20 This is a poor yield as Dr Fjetland, The percent yield for my aldol product was 20%. Theoretical Yield Definition in Chemistry, How to Calculate Theoretical Yield of a Reaction, How to Calculate Limiting Reactant and Theoretical Yield, Limiting Reactant Definition (Limiting Reagent), Redox Reactions: Balanced Equation Example Problem, Example Problem of Mass Relations in Balanced Equations, Heat of Formation Table for Common Compounds, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College, actual yield is the amount of product obtained from a chemical reaction, theoretical yield is the amount of product obtained from the stoichiometric or. Compound MW … Another reason I, could have attained a lower yield is that a lot of the product I created did not make it to, the weigh boat to be massed. This is a preview of subscription content, log in to check access. Chem. An Aldol yield higher … 131, p. 317. First, my product looked visibly, different from most other students. Google Scholar. 198, p. 207. How do I calculate the limiting reagent and percent yield for creating tetraphenylcyclopentadienone in the lab from by aldol condensation. Article  Based on the results of characterization by Fourier transform-infrared spectrometry (FT-IR) and thermogravimetric measurements (TG), it was concluded that the modifier was chemically bonded to the surface of CaO and nearly no Ca(OH)2 was formed during the modification process.
