Ammonium Ferric Citrate Powder Usage and Synthesis.

Ferric ammonium citrate is a commonly used blood tonic and nutritional booster for children or adults who cannot swallow tablets. It contains iron, which can be absorbed into the body and is used to treat iron deficiency anemia.

Ammonium ferric citrate is not absorbed until it is reduced to inorganic ferrous salts in the body. The upstream products of Ammonium Ferric Citrate, Sodium and Potassium Citrate, can be used as anticoagulants, antacids, flavoring agents and in the preparation of various pharmaceuticals. Ammonium ferric citrate also has the function of anti-caking agent, which can prevent the caking of table salt.

Uses and Function of Ammonium Ferric Citrate.

Ammonium ferric citrate is an excellent nutrient fortifier, which can be used as a blood tonic to treat iron deficiency anemia, and is widely used in food additives, pharmaceuticals and many other fields.

The brown scale-like ammonium ferric citrate contains higher iron content, while the green scale-like ammonium ferric citrate contains lower iron content.

The brown product is used as a blood tonic to treat iron-deficiency anemia; it can be used as a food additive, and its iron content is 16.5%-21.2% according to Japan's "Food Additives Public Definition Book".

Brown and green products are chemically sensitive substances, green products are more light-sensitive than brown products. Paper coated with green ferric ammonium citrate and erythrocyanide (potassium ferricyanide) is known as blue colored paper.

In the exposure, citrate within the trivalent iron for the original bivalent, water that is produced Teng's blue, so the light part of the blue, not the part of the light is still white, can be obtained from the blue background white line pattern.

Ammonium ferric citrate can be used as nutritional supplements, anti-caking agents, iron fortification, anti-anemia with iron (each oral 1 ~ 2g). Can be added to cookies, milk powder.

It is not suitable to be used in food that should not be colored. In addition, it can be used in photographic industry, pharmaceutical industry, bacterial culture medium, aluminum measurement, photography, blue printing, blood supplementation.

Characteristic of Ammonium Ferric Citrate.

Ammonium ferric citrate is a complex salt of unknown structure consisting of iron, ammonia and citric acid. It has various compositions depending on the conditions of manufacture, usually consisting of 16.5% to 18.5% iron; about 9% ammonia and 65% citric acid. Transparent thin scales or granules of brown, reddish-brown or sauce-red color, or brownish-yellow powder.

Odorless or slightly ammonia odor and mild iron metal flavor. Easily deliquesced in air and affected by light (hydrolyzed). Prone to mold. Extremely soluble in water (1g/0.5m1), aqueous solution nearly neutral, insoluble in ethanol and ether.5% aqueous solution of Ph value of about 5.0 ~ 8.0.

Product Methods of  Bulk Ammonium Ferric Citrate Powder.

Dissolve the iron hydroxide in citric acid, and with ammonia and, then after drying and obtained.

(1) Preparation of iron hydroxide add ferrous sulfate into water, add sulfuric acid under stirring, then add sodium chlorate aqueous solution. Then stir vigorously, the temperature rises to above 80 ℃, and then add sodium chlorate. Stirring until the reaction is terminated (check with potassium ferricyanide does not show ferrous reaction), get iron sulfate solution.

Add this solution into the reaction tank, add sodium hydroxide solution, stirring vigorously, the reaction temperature is 80-90 ℃, the reaction liquid from viscous to thin, add water to wash until the sulfate and chlorine meet the requirements. Drain to get iron hydroxide.

(2) ferric ammonium citrate preparation of citric acid, iron hydroxide and water into the reaction tank, stirring, the temperature is controlled at 95 ° C or more, holding 1h. Then cooled to 50 ° C, stirring through the ammonia. Let stand for more than 48h. The supernatant was taken and filtered, and the filtrate was concentrated into a paste and dried at 80°C to obtain ammonium ferric citrate. The total yield to ferrous sulfate was 73-75%.
