------------------------------------------------ **Synthesis of trans-p-Anisalacetophenone**

**1. Prepare a Table:**
- **List all chemicals used in the procedure along with their purpose.**

**2. Data Required:**
- **Melting Point of trans-p-Anisalacetophenone** (include source)
- **Molar Mass of trans-p-Anisalacetophenone** (include source)

**Procedure:**

1. Carefully measure 1.0 mL each of p-anisaldehyde and acetophenone. Place them in a screw-cap test tube.
2. Add 3.0 mL of 95% ethanol. Shake the test tube gently to achieve a homogeneous mixture.
3. Using the pipet provided, add 6-7 drops of 40% sodium hydroxide solution to the ethanolic solution.
4. Shake the mixture for several minutes until the solution becomes homogeneous again. Allow the solution to sit at room temperature for 15 minutes with occasional shaking.
5. Crystals often form within the 15-minute period. If not, cool the reaction mixture in an ice-water bath until crystals form. If crystals do not form, ask the instructor for a seed crystal.
6. Collect the product on filter paper using vacuum filtration. Use deionized water to rinse your test tube and wash the precipitate.
7. Begin heating about 15 mL of ethanol for recrystallization.
8. Dissolve the impure trans-p-anisalacetophenone in a small amount of hot ethanol in a beaker until the solution is a clear light yellow.
9. If the solid does not dissolve, add deionized water with a dropper while simmering. When cloudiness appears, slow the addition of water. Continue until there is slight cloudiness.
10. Add hot ethanol dropwise until the cloudiness disappears. Remove from heat.
11. Let the solution cool to room temperature, then place it on ice.
12. Once cold and crystals have formed, collect the crystals by vacuum filtration using a weighed filter. Rinse the crystals with ice-cold ethanol and allow them to dry by pulling air through the crystals for 10 minutes.
13. Weigh the product and calculate the percent yield. Determine its melting point and obtain an IR spectrum. Turn in a sample to your instructor.
