Yield: 85%

Reaction Conditions:

Stage #1:citric acid with sodium hydroxide in water for 0.5 h;
Stage #2: with iron(III) chloride hexahydrate in water at 50 - 55; for 1 h;

Steps:

2 Example-2: Preparation of Ferric Citrate
Example-2: Preparation of Ferric Citrate To a 2.0 L four-neck round bottom flask, 200 ml purified water and 44.4 gm sodium hydroxide were added and stirred to make a solution. To the reaction mass, 77.7 gm citric acid monohydrate was added and stirred for 30 minutes. Thereafter, 100 gm ferric chloride hexahydrate was added to the reaction mass and further stirred fori hour at 50-55°C. The reaction mass was cooled to 25 °C and subsequently, 1200 ml of methanol was slowly added to the reaction mass and stirred for 1 hour. Precipitated product was filtered and washed with 100 ml of methanol. The wet product was dried under reduced pressure. Yield: 85% molar yield Description: dark brown colored to red colored powder
