Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...

This is a dry lab assessment for synthesis of Nylon 6,6. I believe I understand how to calculate the limiting reagent (Q1) and have determined it to be adipic acid. I’m stuck on calculating the theoretical yield (Q2) and need some help getting through the bullet points of the procedure used to answer the question. Thanks! 1. In the experiment, you are instructed to use 0.500 g of adipic acid and 0.40 g of hexamethylenediamine. Calculate the mmol of each...
