In an Amide Synthesis reaction between acetic anhydride & an unknown primary amine with aluminum oxide.
"1. Why is it essential that no water or alcohols are present during the amide synthesis reaction you performed in lab this week? Acetic anhydride can be quenched simply by washing the reaction mixture with water. Provide the balanced equation for the reaction of acetic anhydride and water below."
Homework Answers
If water present during the amide synthesis reaction acetic acid will be produced from acetic anhydride.
If alcohols present during the amide synthesis reaction ester will be formed from the acetic anhydride.
Due to the above reactions some of the acetic anhydride can be involved in above reactions. Then yield of the amide synthesis reaction will be decreased.
Balanced equation for the reaction of acetic anhydride and water.

Multistep Synthesis: Synthesis of Amine (Organic Chemistry
Lab)
Question
1. Explain each step of reaction mechanism. (How does it
work?)
2. Discuss reason for reaction sequence. (Why must one reaction
occur before another?)
3. Explain how IR supports the major product.
Experiment Procedure
Imine Formation:
Weigh a 20 mL beaker and then add 380 mg of ortho-vanillin and
268 mg of para-toluidine. Care should be taken to add equivalent
molar amounts of the two reactants.
Observe the mixture and record...

PRELAB EXERCISE EXPERIMENT 21 Synthesis of Aspirin (Acetylsalicylic Acid) What is the purpose of sulfuric acid or phosphoric acid used in the acetylation reaction? Use equations to explain this purpose. The procedure calls for cautious addition of water to the reaction mixture while it is still hot. What purpose does the addition of water serve and why should the addition be done while the reaction mixture is hot? Provide an equation for the reaction involved.Using the quantities of salicylic acid and acetic anhydride...
