In two to three pages write the experimental section of the lab report forThe Synthesis of Sulfanilamide. I will attach a lab report example, look at theexperimental section that starts at page 7, and use that as an example of how it should be written. I will also attache the general procedure for this lab in which you will use in writing this section.
thank you and let me know if you have any quotations.

Purpose: You will carry out the multi-step synthesis of the epoch-making antibacterial drug, sulfanilamide. Reactions and Physical Properties: Procedure: Day 1 (3/19): Carry out everything in the hood! To a dry dram vial with a stir bar, add dichloromethane (0.5 mL) and aniline (2.50 mmol). Immediately cap the vial with a rubber septum. Place this vial in a cold water bath. To a separate dry dram vial, add dichloromethane (0.5 mL) and trifluoroacetic anhydride (TFAA, 3.54 mmol). TFAA hydroyzes rapidly in moist air, so make the transfer quickly. Using a needle, add the TFAA solution dropwise to the aniline solution. You will want to vent the septum with an additional needle. Heat is produced in the reaction. If the addition is too rapid, the methylene chloride starts to reflux and fumes are emitted. After the addition is complete, allow the reaction to stir at ambient temperature for 10 min. Remove the septum from the reaction vial and, in the hood, concentrate the solution on a warm sand bath under a slow stream of air. The crude 2,2,2-trifluoroacetanilide intermediate is obtained as a white powder. Cap the vial. The crude material is not purified further, but rather used directly in the next reaction of the sequence without further characterization. Label the vial, seal the cap with parafilm, and place in the fridge until next week. Day 2 (3/26): Remove your product from the fridge from week 1. Carefully transfer your product and stirbar to a 5-10 mL round-bottom flask, and attach a microscale reflux condenser (you do not need to hook up water to the condenser). Very carefully measure out chlorosulfonic acid (13.7 mmol) into a dry dram vial. CAUTION: Chlorosulfonic acid is a very corrosive substance. It reacts violently with water and causes serious burns on contact with the skin. Dispense the reagent in the hood and wear gloves. Very carefully and slowly add the chlorosulfonic acid to the reaction vessel through the condenser by Pasteur pipet....

SULPANILAMIDE SYNTHESIS
EXPERIMENTAL
The Laboratory synthesis of sulphanilamide involves three steps.
STEP 1 PREPARATION OF 2,2,2-TRIFLOUROACETANILIDE
2,2,2-TRIFLOUROACETANILIDE

2,2,2-triflouroacetanilide can be prepared from aniline using triflouroacetic anhydride and
dichloromethane as solvent. The method of preparation is given below. Being co
osive, all
addition and experimental methods are performed under a fume hood.
0.5 mL of dichloro methane and 2.50 mmol of aniline is added to a dram vial connected with
a stir bar. The vial is immediately covered with a ru
er septum and kept in cold bath. To a
separate dry dram vial, 0.5 mL of dichloromethane and 3.54 mmol of
triflouroaceticanhydride (TFAA) is added very fast to prevent the hydrolysis of TFAA. The
TFFA solution is added to the aniline solution using a needle dropwise. Care is taken for the
addition to be slow, as the reaction is exothermic and produces large amount of heat and
fumes will be...
