Anhydrous ferric chloride (FeCl₃) is a versatile chemical with a wide range of industrial applications. Its highly hygroscopic and corrosive nature makes it particularly useful as a catalyst and Lewis acid in chemical reactions.
1. Chemical Synthesis & Industry
Lewis Acid Catalyst: Widely used as a powerful Lewis acid catalyst in organic synthesis for key reactions, including:
Friedel-Crafts Reaction: For alkylation and acylation of aromatic compounds.
Chlorination: Of aromatic hydrocarbons.
Sulfonation and other electrophilic substitutions.
Oxidizing Agent: Serves as an oxidizing agent in various chemical processes.
Precursor to Hydrated Salts: Used to produce hydrated ferric chloride (FeCl₃·6H₂O) solutions.
2. Water and Wastewater Treatment
Coagulant and Flocculant: Its primary large-scale use is as an highly effective coagulant for:
Drinking Water Purification: Removing suspended particles, organic matter, and phosphates.
Wastewater Treatment: Treating industrial and municipal sewage, particularly for phosphate removal to control eutrophication.
Sludge Conditioning: Dewatering industrial sludges.
3. Electronics and Metal Processing
Etchant for Copper: The most common use in electronics is as an etchant for copper on printed circuit boards (PCBs). It reacts with copper to form soluble cupric chloride, precisely removing unwanted copper.
Etchant for Stainless Steel: Also used in the metalworking industry for etching stainless steel and other alloys.
Chlorination Agent: In metallurgy, it acts as a chlorinating agent for certain metals.
4. Other Applications
Animal Feed Additive: Used in trace amounts as a nutritional supplement for iron.
Pigment Production: Serves as a raw material in the manufacture of iron oxide pigments.
Laboratory Reagent: Used in various analytical and synthetic chemistry procedures.
