Hedef

Bitkisel yağı sodyum hidroksit ile sabunlaştırarak sabun elde etmek ve trigliseritlerdeki ester bağlarının hidrolizini göstermek.

Arka Plan

Saponification is the base-catalyzed hydrolysis of a fat or oil (triglyceride) to produce glycerol and soap (sodium salts of fatty acids). This ancient chemical reaction is the basis of all soap manufacturing and demonstrates ester bond cleavage.

Güvenlik Uyarıları

  • Concentrated NaOH is extremely corrosive
  • Wear nitrile gloves and goggles at all times
  • Hot oil and NaOH can cause severe burns
  • Do not use the soap on skin until it has fully cured (4-6 weeks)

Malzemeler

  • Vegetable oil (olive or coconut) (20 mL)
  • Sodium hydroxide (NaOH) (10 mL)
    6M solution
  • Ethanol (10 mL)
    To help mix oil and base
  • Sodium chloride (NaCl) (15 g)
    Saturated solution for salting out
  • Distilled water (100 mL)

Ekipman

250 mL beaker Hot plate Glass stirring rod Cheesecloth or filter Mold (small cup)

Prosedür

1

Heat 20 mL of vegetable oil in the beaker to about 40°C on the hot plate.

2

Mix 10 mL of 6M NaOH with 10 mL ethanol in a separate container.

2 dak NaOH is corrosive
3

Slowly add the NaOH/ethanol mixture to the warm oil while stirring continuously.

3 dak Hot caustic mixture
4

Continue heating and stirring at 60-70°C for 20 minutes until the mixture becomes thick and opaque (trace).

7

Mold the soap into a shape and allow to dry for 24 hours.

3 dak Do not use on skin until fully cured
8

Test a small piece by dissolving in warm water — it should produce lather.

Beklenen Sonuçlar

A solid, white to cream-colored soap that lathers when dissolved in water. The soap may feel slightly slippery, indicating successful saponification. Full curing takes 4-6 weeks to neutralize any remaining NaOH.

Temizlik

Neutralize any remaining NaOH solution with vinegar before disposal. Rinse all glassware. Wipe down work surfaces.
