Titanium isopropoxide

Titanium isopropoxide is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Titanium isopropoxide rather than just read about it. In short: Titanium isopropoxide, also commonly referred to as titanium tetraisopropoxide or TTIP, is a chemical compound with the formula Ti{OCH(CH3)2}4. This alkoxide of titanium(IV) is used in organic synthesis and materials science.

Key takeaways

Titanium isopropoxide belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Titanium isopropoxide to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Titanium isopropoxide, also commonly referred to as titanium tetraisopropoxide or TTIP, is a chemical compound with the formula Ti{OCH(CH3)2}4. This alkoxide of titanium(IV) is used in organic synthesis and materials science. It is a diamagnetic tetrahedral molecule. Titanium isopropoxide is a component of the Sharpless epoxidation, a method for the synthesis of chiral epoxides. The structures of the titanium alkoxides are often complex. Crystalline titanium methoxide is tetrameric with the molecular formula Ti4(OCH3)16. Alkoxides derived from bulkier alcohols such as isopropyl alcohol aggregate less. Titanium isopropoxide is mainly a monomer in nonpolar solvents.

Preparation It is prepared by treating titanium tetrachloride with isopropanol in presence of ammonia. Hydrogen chloride is formed as a coproduct:

TiCl4 + 4 (CH3)2CHOH → Ti{OCH(CH3)2}4 + 4 HCl

Properties Titanium isopropoxide reacts with water to deposit titanium dioxide:

Ti{OCH(CH3)2}4 + 2 H2O → TiO2 + 4 (CH3)2CHOH This reaction is employed in the sol-gel synthesis of TiO2-based materials in the form of powders or thin films. Typically water is added in excess to a solution of the alkoxide in an alcohol. The composition, crystallinity and morphology of the inorganic product are determined by the presence of additives (e.g. acetic acid), the amount of water (hydrolysis ratio), and reaction conditions. The compound is also used as a catalyst in the preparation of certain cyclopropanes in the Kulinkovich reaction. Prochiral thioethers are oxidized enantioselectively using a catalyst derived from Ti(O-i-Pr)4.

Naming Titanium(IV) isopropoxide is a widely used item of commerce and has acquired many names in addition to those listed in the table. A sampling of the names include: titanium(IV) i-propoxide, isopropyl titanate, tetraisopropyl titanate, tetraisopropyl orthotitanate, titanium tetraisopropylate, orthotitanic acid tetraisopropyl ester, Isopropyl titanate(IV), titanic acid tetraisopropyl ester, isopropyltitanate, titanium(IV) isopropoxide, titanium tetraisopropoxide, iso-propyl titanate, titanium tetraisopropanolate, tetraisopropoxytitanium(IV), tetraisopropanolatotitanium, tetrakis(isopropoxy) titanium, tetrakis(isopropanolato) titanium, titanic acid isopropyl ester, titanic acid tetraisopropyl ester, titanium isopropoxide, titanium isopropylate, tetrakis(1-methylethoxy)titanium.

Applications TTIP can be used as a precursor for ambient conditions vapour phase deposition such as infiltration into polymer thin films.

Worked examples

Example 1 — a first encounter with Titanium isopropoxide

Start with the simplest possible case. Write down what Titanium isopropoxide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Titanium isopropoxide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Titanium isopropoxide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Titanium isopropoxide

In research: Titanium isopropoxide appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Titanium isopropoxide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Titanium isopropoxide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alkoxides, Isopropoxy compounds, Titanium(IV) compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Titanium isopropoxide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
