Muz aromasından sorumlu esterin sentezi

Organic Synthesis Advanced (University) 90 dak ~$22,00

Hedef

Asetik asit ile izoamil alkolün Fischer esterifikasyonuyla izoamil asetat (muz yağı) sentezlemek ve esterlerin meyve aromalarını nasıl oluşturduğunu göstermek.

Arka Plan

Isoamyl acetate is the ester responsible for the characteristic smell of bananas. It is synthesized by the acid-catalyzed reaction of isoamyl alcohol with acetic acid. This experiment demonstrates ester formation, liquid-liquid extraction, and the connection between molecular structure and sensory properties.

Güvenlik Uyarıları

  • Concentrated H₂SO₄ is extremely corrosive
  • Glacial acetic acid causes burns
  • Isoamyl alcohol is flammable
  • Work in a fume hood throughout

Ekipman

Round-bottom flask (100 mL) Reflux condenser Heating mantle Separating funnel Boiling chips

Prosedür

1

Add 5 mL isoamyl alcohol and 7 mL glacial acetic acid to the round-bottom flask with boiling chips.

3 dak Fume hood required
2

Slowly add 1 mL concentrated H₂SO₄ as catalyst.

2 dak Add very slowly — exothermic
3

Attach reflux condenser and heat at gentle reflux for 60 minutes.

60 dak Ensure condenser water flows
4

Cool and transfer to a separating funnel. Add 25 mL water and shake.

3 dak
5

Wash the organic layer with 25 mL of 5% NaHCO₃. Vent frequently.

5 dak CO₂ produced — vent
6

Dry the organic layer over Na₂SO₄ for 10 minutes. Filter and smell by wafting.

12 dak Waft — do not sniff directly
7

Calculate the yield and record the banana-like aroma.

5 dak

Beklenen Sonuçlar

A clear, pale yellow liquid with a strong banana aroma (isoamyl acetate). Typical yield is 50-65%. The unmistakable banana smell confirms successful ester formation.

Temizlik

Dispose of organic waste in designated containers. Neutralize acid waste. Rinse glassware with acetone then water.
