Meaning and Usage

"Octadecyl" refers to a chemical entity relating to or derived from octadecane, which is a straight-chain hydrocarbon with eighteen carbon atoms. It is often used in the context of organic chemistry and materials science, describing long carbon chains in various compounds.

Frequency of Use: The term is not frequently used in everyday conversation and is mostly limited to scientific literature, research, and industrial contexts.

Context of Use: It is predominantly used in written contexts, as it relates to a technical vocabulary within chemistry and materials science.

Example Sentences

1. "The researchers synthesized a novel octadecyl silane to modify the surface properties of silicon wafers."

2. Исследователи синтезировали новый октадецилсилан для изменения свойств поверхности кремниевых пластин.

3. "Octadecyl chains are commonly used in the formulation of surfactants and emulsifiers."

4. Октадецильные цепи обычно используются в формулировке сурфактантов и эмульгаторов.

5. "In this study, octadecyl groups were introduced to enhance hydrophobicity."

Idiomatic Expressions

The word "octadecyl" is primarily used in a scientific context, but it does not have significant idiomatic expressions associated with it. However, given its relation to long carbon chains, one might discuss broader chemistry concepts involving long-chain hydrocarbons:

1. "They are working on a project involving long-chain molecules, such as octadecyl compounds."

2. Они работают над проектом, связанным с молекулами с длинными цепями, такими как октадециловые соединения.

3. "The impact of octadecyl functionality in polymers can greatly affect their performance."

4. Влияние октадециловой функциональности в полимерах может значительно повлиять на их производительность.

5. "In materials science, the presence of octadecyl groups can alter the properties of the final product."

6. В материаловедении наличие октадецильных групп может изменить свойства конечного продукта.

Etymology

The term "octadecyl" comes from "octadecane," which derives from the roots "octa-" (meaning eight) and "deca-" (meaning ten), referring to a compound with a total of eighteen carbon atoms in a linear arrangement. The suffix "-yl" indicates it is a radical or branch derived from such compounds.

Synonyms and Antonyms

Synonyms: - Octadecane derivative - Long-chain alkyl

Antonyms: - Short-chain alkyl - Non-carbon-based compounds

In summary, "octadecyl" is a specialized term used primarily in scientific contexts related to chemistry, particularly when discussing materials or surfaces that involve long carbon chains.
