Sodium diacetate is produced by reacting sodium carbonate or sodium hydroxide with acetic acid under controlled conditions.
Na₂CO₃ + 4CH₃COOH → 2NaH(C₂H₃O₂)₂ + CO₂ + H₂O
1️⃣ Reaction Formation: Sodium carbonate (Na₂CO₃) reacts with acetic acid (CH₃COOH) to form sodium diacetate.
2️⃣ Kết tinh: The solution is evaporated to obtain solid sodium diacetate.
3️⃣ Sấy khô và đóng gói: The final product is dried and packed in moisture-resistant bags.
Raw Materials Required:
Natri Cacbonat (Na₂CO₃) hoặc Natri Hiđroxit (NaOH)
Glacial Acetic Acid (CH₃COOH, >99%)
