• Alkanes are discussed in research papers.

基础例句

In science class, we learned that alkanes are a type of hydrocarbon.

在科学课上,我们学到烷烃是一种碳氢化合物。

Methane is the simplest alkane and is found in natural gas.

甲烷是最简单的烷烃,存在于天然气中。

Alkanes are often used as fuels because they burn cleanly.

烷烃常被用作燃料,因为它们燃烧时很清洁。

The teacher explained that alkanes have single bonds between carbon atoms.

老师解释说,烷烃的碳原子之间是单键连接。

高级例句

In petroleum refining, alkanes are separated through fractional distillation to produce various fuels.

在石油精炼中,烷烃通过分馏分离,以生产各种燃料。

The chemical stability of alkanes makes them suitable for use in industrial lubricants and solvents.

烷烃的化学稳定性使其适用于工业润滑剂和溶剂。

常见错误

❌ 错误:Alkane is a type of alcohol.
✓ 正确:Alkane is a type of hydrocarbon.

错误:将alkane误认为是酒精(alcohol),实际上alkane是碳氢化合物,不含氧原子,而alcohol含有羟基(-OH)。正确用法应强调其碳氢组成。

❌ 错误:I use alkane to clean my hands.
✓ 正确:I use alkane-based solvents in the lab.

错误:在日常场景中误用alkane,它主要用于专业或工业语境。正确用法应限定在化学或工程领域,例如作为溶剂成分。

近义词辨析

hydrocarbon

hydrocarbon是更广泛的术语,指所有碳氢化合物,包括烷烃、烯烃等;而alkane特指饱和烃,碳原子间只有单键。

Alkanes are a subset of hydrocarbons, with all bonds being single.

paraffin

paraffin在非正式语境中可指烷烃,但更常指石蜡(一种固体烷烃混合物)或煤油;alkane是更准确的化学术语。

Paraffin wax consists mainly of alkanes with longer carbon chains.
