• Berat Molekul: 142.09 g/mol

• Nombor CAS: 126-96-5

• Nombor E: E262(ii)

Key Functional Properties

✔ Buffered pH Control – Maintains stable pH in food and industrial applications.
✔ Antimicrobial Activity – Inhibits bacterial and mold growth.
✔ Preservative Effect – Extends food shelf life.
✔ Penambah Perisa – Provides a mild vinegar-like taste in seasonings.
✔ Perencatan Kakisan – Used in industrial applications for metal protection.

Sodium diacetate is produced by reacting sodium carbonate or sodium hydroxide with acetic acid under controlled conditions.

Reaction Equation:

Na₂CO₃ + 4CH₃COOH → 2NaH(C₂H₃O₂)₂ + CO₂ + H₂O

Proses Pengeluaran:

1️⃣ Reaction Formation: Sodium carbonate (Na₂CO₃) reacts with acetic acid (CH₃COOH) to form sodium diacetate.
2️⃣ Penghabluran: The solution is evaporated to obtain solid sodium diacetate.
3️⃣ Pengeringan & Pembungkusan: The final product is dried and packed in moisture-resistant bags.

Raw Materials Required:

• Natrium Karbonat (Na₂CO₃) atau Natrium Hidroksida (NaOH)

• Glacial Acetic Acid (CH₃COOH, >99%)
