- Look up and provide the boiling point and structure of the xylenes solvent. Based on the structure, what kind of solvent (polar aprotic, polar protic, or nonpolar) is xylenes? Based on the boiling point of xylenes, why do we wash with a small amount of ethyl acetate (bp = 77 °C) to facilitate drying of the isolated product?

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...

Experiment: A mixture of equal proportions of benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene are to be separated by extraction using the solvent diethyl ether. Day 1: Part A. Isolation of the basic component: In a small beaker, dissolve 3 g of the mixture (benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene) in 30 mL of diethyl ether and transfer the mixture to a 125- mL separatory funnel (see Fig. 1) using a little diethyl ether to complete the transfer. Add 10 mL...

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...
