Procedure - Scale this procedure to use 1.25 mmol of your Aromatic Amine Formation of Diazonium Salt: Il your aromatic amine is sulfanilic acid, first dissolve 0.5 g sodium carbonate in 20 mL water and then add 10 mmol sulfanilic acid to the solution and heat gently. Add additional sodium carbonate as needed to assist in the dissolution of the solid and then perform a hot gravity filtration to remove any suspended material that does not dissolve. Cool the flask to room temperature. Add 0.69 g sodium nitrite and stir. Pour this solution into a cooled beaker containing 9.25 mL of 2M HCI. For all other aromatic amines, heat gently a solution of 10 mmol your aromatic amine in 8 mL of 3M HCI. If your solid does not dissolve, add up to 10 mL water gradually until it is all dissolved. While stirring, cool to 5 °C in an ice bath and add 10 mL of IM sodium nitrite while keeping the temperature below 10 °C. Use a starch-iodide test, dilute I drop of reaction mixture in 1 ml water and apply 1 drop of this solution to Kl-starch test paper, to determine if the nitrite is in excess - a dark blue/black spot will form. Add sodium nitrite (1M) dropwise until you receive a positive test. Keep this solution in the ice bath while you prepare the coupling partner. Preparation of Coupling Partner: If your coupling partner is a phenol, dissolve 10 mmol of the phenol in 20 mL of IM NaOH (if your phenol has additional acid protons, account for that in the total volume of NaOH used) and cool in an ice bath. While cooling, slowly add the diazonium salt with stirring and leave the mixture in the ice bath for 15 min or more until crystallization is complete. If little or no solid appears, adjust the pH with dilute HCl or NaOH to induce crystallization If your coupling partner is an amine, dissolve 10 mmol of the amine in 10 mL IM HCI (if your amine has additional basic groups, account for that in the total volume of HCl used) and cool in an ice bath. While cooling, slowly add the diazonium salt with stirring and leave the mixture in the ice bath for 15 min or more. Neutralize the solution with 3M aq. sodium carbonate and allow to stand in the ice bath until crystallization is complete.
2. Please draw the structure of the dye you will be synthesizing below, Dye#: 17 HO 3. Please draw the two coupling partners you will be utilizing in your synthesis. OH NH2 4. Calculate the theoretical yield for the synthesis of your dye.
