As we all know, ferric chloride is very important both for chemical production and as an aid to laboratory experiments. Today I will summarize the seven uses of ferric chloride for your reference.

【Purpose 1】

Mainly used as water treatment agent, also used as mordant, catalyst, chlorinating agent, and used to manufacture other iron salts, etc. Mainly used for water purification, also used for printing board, pigment, dye and medicine, etc.

【Purpose 2】

Used as analytical reagent and electronic device corrosion agent

【Purpose 3】

Used as analytical reagent and TLC developer

【Purpose 4】

It is used as a water purifying agent for drinking water and as a sedimentation agent for wastewater treatment and purification. For printed circuits as etchant. 【Purpose 5】

It is mainly used as a water purifier for drinking water and a sedimentation agent for wastewater treatment and purification. In the printing and dyeing industry, it is used as an oxidizing agent and a printing and dyeing mordant for indigo dyeing. Catalysts for organic synthesis of dichloroethane, etc. Chlorinated leaching agent for silver and copper ores. Etchant for photographic and printing plates. Raw materials for the manufacture of iron salts such as iron phosphate, medicines, pigments and inks. After infiltrating its solution in building concrete, it can increase building strength, corrosion resistance and prevent water seepage. It is used in the production of electronic industry circuit boards and fluorescent digital tubes. Coagulant for recovering glycerin from waste liquid from soap production.

【Purpose 6】

Nutritional supplements (iron fortifiers). Used in baby milk powder, weaning food, etc.

It can combine with β-globulin in milk to form protein iron, which is easily absorbed in the body. Because of its strong acidity, it is not suitable to add directly. It is usually added after it is made into whey iron by reacting with whey. The amount of whey iron added in the above foods is 1.0% to 1.5%.

Iron generally promotes fat oxidation in foods. Whey iron bound to protein does not promote oxidation.

【Purpose 7】

It is mainly used as corrosive agent in industrial water treatment, photography and printing plate making, catalyst and oxidant in organic synthesis industry, oxidant and mordant in dye industry to manufacture other iron salts, pigments, inks, pharmaceutical raw materials and other high-purity grades (99.99%) in Gas-phase co-reduction with metal halides under the action of hydrogen produces separable intermetallic compounds with thermal and electrical conductivity, magnetic induction and oxidation resistance.
