Sym tribromoaniline synthesis 1minute video

Introduction

In this article, we detail the synthesis of tribromoaniline, highlighting the step-by-step process of the reaction. The following instructions summarize the procedure used in the synthesis.

Materials Required

• 15 milliliters of vanillin
• 250 milliliter beaker
• 50 milliliters of glacial acetic acid
• Aniline
• 20 milliliters of bromine
• 100 milliliter Erlenmeyer flask
• Separatory funnel
• Vacuum filtration setup
• 70% ethanol solution for recrystallization

Procedure

1. Measure out 15 milliliters of vanillin and transfer it into a 250 milliliter beaker. Turn on the stirring mechanism to ensure proper mixing.

2. Add 50 milliliters of glacial acetic acid to the aniline in the beaker. It is crucial to maintain a steady stirring throughout this process.

3. Next, measure 20 milliliters of bromine and transfer it to a 100 milliliter Erlenmeyer flask.

4. Add another 50 milliliters of glacial acetic acid to the bromine in the flask.

5. Transfer the bromine-acetic acid mixture into a separatory funnel.

6. Gradually add the bromine solution dropwise to the aniline solution in glacial acetic acid. During this addition, observe the formation of a white precipitate; this indicates the formation of crude tribromoaniline.

7. Once the reaction is complete, perform vacuum filtration on the crude product to isolate the solid.

8. Allow the crude product to dry thoroughly.

9. To purify the product, recrystallize the crude tribromoaniline using a solution of 70% ethanol.

10. Finally, perform suction filtration on the recrystallized crystals and wash them several times with glacial ethanol to yield the final product.

Following these steps will result in the successful synthesis of tribromoaniline.

FAQ

Q: What is tribromoaniline?
A: Tribromoaniline is an aromatic compound that contains three bromine atoms attached to an aniline moiety.

Q: Why is glacial acetic acid used in this synthesis?
A: Glacial acetic acid serves as a solvent in the reaction and helps to facilitate the bromination process of aniline.

Q: How do you know that the reaction is complete?
A: The formation of a white precipitate indicates that the reaction has occurred and that crude tribromoaniline has formed.

Q: What is the purpose of recrystallization?
A: Recrystallization is used to purify the crude product by dissolving it in a suitable solvent and allowing it to crystallize out of solution to remove impurities.

Q: How is vacuum filtration advantageous in this process?
A: Vacuum filtration allows for more efficient separation of the solid product from the liquid, yielding a cleaner product faster than traditional filtration methods.
