TiCl 3 is produced usually by reduction of titanium(IV) chloride.Older reduction methods used hydrogen: [4]. 2 TiCl 4 + H 2 → 2 HCl + 2 TiCl 3. It can also be produced by the reaction of titanium metal and hot, concentrated hydrochloric acid; the reaction does not proceed at room temperature, as titanium is passivated against most mineral acids by a thin surface layer of titanium dioxide.
The McMurry reaction of benzophenone. The McMurry reaction is an organic reaction in which two ketone or aldehyde groups are coupled to form an alkene using a titanium chloride compound such as titanium(III) chloride and a reducing agent. The reaction is named after its co-discoverer, John E. McMurry.
Titanium(III) compounds are characteristically violet, illustrated by this aqueous solution of titanium trichloride. Titanium tetrachloride (titanium(IV) chloride, TiCl 4 [ 18 ] ) is a colorless volatile liquid (commercial samples are yellowish) that, in air, hydrolyzes with spectacular emission of white clouds.
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
The dimeric titanium(III) complex reversibly dissociates to the monomer Cp 2 TiCl. This 15 electron species is Lewis acidic and thus binds epoxides and carbonyl compounds. [33] The complex transfers a single electron to the coordinated substrate generating an alkyl centered radical and an oxygen bound titanium(IV) species. This process is ...
Compounds of titanium in the +2 oxidation state are rarer, examples being titanocene dicarbonyl and Ti(CH 3) 2 2. [Ti(CO) 6] 2− is formally a complex of titanium in the oxidation state of −2. [4] Although Ti(III) is involved in Ziegler–Natta catalysis, the organic derivatives of Ti(III) are uncommon. One example is the dimer [Cp 2 Ti III ...
Under steady state conditions the chloride process is a continuous cycle in which chlorine changes from the oxidized state to the reduced state and reverse. The oxidized form of the chlorine is molecular chlorine Cl 2, the reduced form is titanium tetrachloride (TiCl 4). The oxidizing agent is molecular oxygen (O 2), the reducing agent is coke ...
A stream of titanium tetrachloride gas is added to a stream of molten sodium; the products (sodium chloride salt and titanium particles) is filtered from the extra sodium. Titanium is then separated from the salt by water washing. Both sodium and chlorine are recycled to produce and process more titanium tetrachloride. [78]
