Oxamide

Oxamide 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 Oxamide rather than just read about it. In short: Oxamide is the organic compound with the formula (CONH2)2. This white crystalline solid is soluble in ethanol, slightly soluble in water and insoluble in diethyl ether.

Key takeaways

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

Reference excerpt

Oxamide is the organic compound with the formula (CONH2)2. This white crystalline solid is soluble in ethanol, slightly soluble in water and insoluble in diethyl ether. Oxamide is the diamide derived from oxalic acid, and the hydrate of cyanogen.

Preparation Oxamide is produced from hydrogen cyanide, which is oxidized to cyanogen, which is then hydrolyzed. It can also be prepared from formamide by glow-discharge electrolysis. It can also be prepared from ammonium oxalate via pyrolysis.

Application The main application is as a substitute for urea in fertilizers. Oxamide hydrolyzes (releases ammonia) very slowly, which is sometimes preferred vs the quick release by urea. It is used as a stabilizer for nitrocellulose preparations. It also finds use in APCP rocket motors as a high performance burn rate suppressant. The use of oxamide in concentrations of 1-3 wt% has shown to slow the linear burn rate while having minimal impact on propellant specific impulse. N,N'-substituted oxamides are supporting ligands for the copper-catalyzed amination and amidation of aryl halides in Ullmann-Goldberg reaction, including relatively unreactive aryl chloride substrates.

Reactions It dehydrates above 350 °C releasing cyanogen. Oxamide derivatives form self-assembled monolayers consisting of a hydrogen bonded network.

Worked examples

Example 1 — a first encounter with Oxamide

Start with the simplest possible case. Write down what Oxamide 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 Oxamide 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 Oxamide 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 Oxamide

In research: Oxamide 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 Oxamide 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: Oxamide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carboxamides, Organic compounds with 2 carbon atoms, so understanding it makes those chapters shorter.
In everyday life: Look for Oxamide 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.

Frequently asked questions

What is Oxamide in simple terms?

Oxamide is the organic compound with the formula (CONH2)2. This white crystalline solid is soluble in ethanol, slightly soluble in water and insoluble in diethyl ether.

Why does Oxamide matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Oxamide?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
