Editing Titanium tetrachloride (section)

===Alcoholysis and related reactions===
A characteristic reaction of {{chem2|TiCl4}} is its easy [[hydrolysis]], signaled by the release of [[hydrochloric acid|HCl]] vapors and [[titanium oxide]]s and [[oxychloride]]s. Titanium tetrachloride has been used to create naval [[smoke-screen|smokescreens]], as the hydrochloric acid aerosol and titanium dioxide that is formed scatter light very efficiently. This smoke is corrosive, however.<ref name="ullmann" />

Alcohols react with {{chem2|TiCl4}} to give alkoxides with the formula {{chem2|[Ti(OR)4]_{''n''}|}} (R = [[alkyl]], ''n'' = 1, 2, 4). As indicated by their formula, these [[alkoxide]]s can adopt complex structures ranging from monomers to tetramers. Such compounds are useful in [[materials science]] as well as [[organic synthesis]]. A well known derivative is [[titanium isopropoxide]], which is a monomer. [[Titanium bis(acetylacetonate)dichloride]] results from treatment of titanium tetrachloride with excess [[acetylacetone]]:<ref name=IS>{{cite journal|first1=C.

Organic [[amine]]s react with {{chem2|TiCl4}} to give complexes containing amido ({{chem2|R2N−}}-containing) and imido ({{chem2|RN(2−)}}-containing) complexes. With ammonia, [[titanium nitride]] is formed. An illustrative reaction is the synthesis of [[tetrakis(dimethylamido)titanium]] {{chem2|Ti(N(CH3)2)4}}, a yellow, benzene-soluble liquid:<ref>{{cite journal|first1= D.
