Web2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl. For the preparation of ferrocene ferrous chloride is generated in situ by comproportionation of FeCl 3 with iron powder in tetrahydrofuran (THF). ... Lawrencite, (Fe,Ni)Cl 2, is the natural counterpart, and a typically (though rarely occurring) meteoritic mineral. Several hundred thousand kilograms of anhydrous iron(III) chloride are produced annually. The principal method, called direct chlorination, uses scrap iron as a precursor: 2 Fe + 3 Cl2 → 2 FeCl3 The reaction is conducted at several hundred degrees such that the product is gaseous. Using excess chlorine … See more Iron(III) chloride describes the inorganic compounds with the formula FeCl3(H2O)x. Also called ferric chloride, these compounds are available both in an anhydrous and hydrated forms. They are common source of … See more All forms of ferric chloride are paramagnetic, owing to the presence of five unpaired electrons residing in 3d orbitals. This electronic configuration places electrons in molecular orbitals that are antibonding with respect to ligands. Thus, iron(III) … See more Water treatment In the largest application iron(III) chloride is used in sewage treatment and drinking water production as a coagulant and flocculant. In this application, an aqueous solution of FeCl3 is treated with base to form a See more 1. Lide DR, ed. (1990). CRC Handbook of Chemistry and Physics (71st ed.). Ann Arbor, MI, USA: CRC Press. ISBN 9780849304712 See more The reactivity of ferric chloride reveals two trends: It is a Lewis acid and an oxidizing agent. Lewis-acid reactions Reactions of iron(III) chlorides reflect the description of iron(III) as oxophilic and a hard Lewis acid. … See more Anhydrous iron(III) chloride is harmful, highly corrosive, and acidic.
