Ammonia Ferric Citrate: Formulas and Manufacturing Process

Ammonia ferric citrate is a chemical compound widely used in pharmaceuticals, food additives, and industrial applications. Understanding its formulas and manufacturing process is essential for quality production.

Chemical Formula and Properties
Ammonia ferric citrate has the general formula NH₄FeC₆H₅O₇ (ammonium iron(III) citrate). It exists in two forms:
– Green form: Soluble in water, used in medical applications like iron supplements.
– Brown form: Less soluble, primarily for industrial uses.

Key properties include high solubility in water, stability under controlled conditions, and its role as an iron source.

Manufacturing Process
The production of ammonia ferric citrate involves the following steps:

1. Raw Material Preparation
– Citric acid and ferric hydroxide (or iron(III) oxide) are mixed in a reactor.
– Ammonia solution is added to adjust pH and facilitate complex formation.

2. Reaction and Synthesis
– The mixture is heated to 60–80°C to enhance reactivity.
– Ferric ions (Fe³⁺) bind with citrate ions, forming ferric citrate.
– Ammonia neutralizes excess acid, yielding ammonia ferric citrate.

3. Purification and Crystallization
– The solution is filtered to remove impurities.
– Evaporation or cooling crystallization isolates the product.

4. Drying and Packaging
– The crystals are dried at controlled temperatures.
– Final product is packed in airtight containers to prevent moisture absorption.

Applications
– Pharmaceuticals: Iron supplements for treating anemia.
– Food Industry: Fortification agent in dietary products.
– Industrial Uses: Water treatment and chemical synthesis.

Conclusion
Ammonia ferric citrate production requires precise control of pH, temperature, and purification. Its versatile applications make it a valuable compound in multiple industries. Proper manufacturing ensures high purity and efficacy.
