O-Cresyl glycidyl ether

O-Cresyl glycidyl ether is a science 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 O-Cresyl glycidyl ether rather than just read about it. In short: o-Cresyl glycidyl ether (ortho-cresyl glycidyl ether, o-CGE) is a liquid aromatic organic chemical compound and chemically a glycidyl ether. It has the formula C10H12O2 and the CAS Registry Number 2210-79-9.

Key takeaways

O-Cresyl glycidyl ether belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect O-Cresyl glycidyl ether to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of O-Cresyl glycidyl ether from memory before moving on to harder problems.

Reference excerpt

o-Cresyl glycidyl ether (ortho-cresyl glycidyl ether, o-CGE) is a liquid aromatic organic chemical compound and chemically a glycidyl ether. It has the formula C10H12O2 and the CAS Registry Number 2210-79-9. It is one of a number of glycidyl ethers available commercially that are used to reduce the viscosity of epoxy resins. These are then further used in coatings, sealants, adhesives, composites and elastomers.

Uses The main use of o-CGE is to reduce the viscosity of epoxy resins. These reduced viscosity resins may then be used to formulate coatings including UV cured versions. It is a monofunctional diluent and so in polymer science terms is a chain terminator. Chain extenders (f = 2) and cross linkers (f ≥ 3) are low molecular weight di or tri-functional epoxy diluents. The use of the diluent does effect mechanical properties and microstructure of epoxy resins. As it has glycidyl functionality, it is classed as a Reactive diluent.

Other names o-CGE is known by a number of other names. These include:

Oxirane, 2-[(2-methylphenoxy)methyl]- Propane, 1,2-epoxy-3-(o-tolyloxy)- Oxirane, [(2-methylphenoxy)methyl]- 2-[(2-Methylphenoxy)methyl]oxirane 1-(o-Methylphenoxy)-2,3-epoxypropane

Toxicology The material is a skin irritant and skin sensitizer. The toxicology has been reasonably well studied. It is REACH registered and produced or imported into the European Union in quantities greater than one thousand tonnes per annum.

Worked examples

Example 1 — a first encounter with O-Cresyl glycidyl ether

Start with the simplest possible case. Write down what O-Cresyl glycidyl ether claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 O-Cresyl glycidyl ether 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 O-Cresyl glycidyl ether 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 O-Cresyl glycidyl ether

In research: O-Cresyl glycidyl ether appears in science 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 O-Cresyl glycidyl ether 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: O-Cresyl glycidyl ether is common in secondary-school and first-year university syllabi. It links to neighbouring topics Glycidyl ethers, Reactive diluents, so understanding it makes those chapters shorter.
In everyday life: Look for O-Cresyl glycidyl ether 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.
