mixture of trans-cinnamic acid,
4-phenylphenol, and nicotinamide by extraction?
thank you
Procedure Your mission is to separate a mixture of trans-cinnamic acid, 4-phenylphenol, and nicotinamide by extraction. Start by dissolving/suspending two grams of the mixture in approximately 50 mL of diethyl ether. (Caution: Diethyl ether is extremely flammable! Extract the ether twice with -25 mL of 5% HCl and then twice with -25 mL 5% sodium bicarbonate. It...

Imagine a biochemistry lab is testing out a new procedure to improve the synthesis of a dipeptide molecule made with the amino acids Valine and Threonine. The hypothesis is that acid as a catalyst will improve the condensation reaction between the amino acids and create a greater yield of a dipeptide (molecule formed with these two amino acids). The procedure compares the result of 10 samples using the common older procedure (A) to ten samples using the newer acid synthesis...
