氢化是一种化学过程,指在催化剂作用下,将氢气与有机化合物反应,使其不饱和度降低或性质改变。

用法要点

句型搭配

hydrogenation 通常用作不可数名词,描述过程或结果;常见于被动语态或与过程动词搭配,强调化学变化。

• undergo hydrogenation
• the hydrogenation of fats
• catalyze hydrogenation

介词用法

常用介词 of 表示氢化的对象(如油脂),with 表示使用的氢气,in 表示反应条件或领域。

• hydrogenation of vegetable oil
• hydrogenation with hydrogen gas
• hydrogenation in food processing

语域说明

hydrogenation 是专业术语,主要用于化学、食品科学、医学等学术或工业语境,日常对话中较少使用。

• industrial hydrogenation
• medical hydrogenation therapy
• academic research on hydrogenation

基础例句

In cooking, hydrogenation makes oils more solid, like in margarine.

在烹饪中,氢化使油脂更固态,例如人造黄油。

The hydrogenation of vegetable oil reduces its unsaturated fats.

植物油的氢化降低了其不饱和脂肪含量。

This chemical process involves hydrogenation to change the product's properties.

这个化学过程涉及氢化,以改变产品的性质。

高级例句

The industrial hydrogenation of alkenes is a key step in petroleum refining to produce saturated hydrocarbons.

烯烃的工业氢化是石油精炼中生产饱和烃的关键步骤。

Recent studies show that selective hydrogenation can improve the efficiency of pharmaceutical synthesis.

最近研究表明,选择性氢化能提高药物合成的效率。

In food science, hydrogenation is used to extend shelf life, but it may create trans fats.

在食品科学中,氢化用于延长保质期,但可能产生反式脂肪。

常见错误

❌ 错误:The hydrogenation is a good process.
✓ 正确:Hydrogenation is a good process.

hydrogenation 作为不可数名词,泛指过程时通常不加冠词 the;加 the 特指某个具体氢化过程,如 the hydrogenation we discussed。

❌ 错误:They hydrogenation the oil.
✓ 正确:They perform hydrogenation on the oil.

hydrogenation 是名词,不能直接作动词;应使用动词如 perform、undergo 或 catalyze 搭配,表示进行氢化。

近义词辨析

hydrogenolysis

hydrogenation 指加氢反应,通常不破坏分子骨架;hydrogenolysis 指加氢裂解,涉及化学键断裂,生成较小分子。

Hydrogenation saturates double bonds, whereas hydrogenolysis breaks carbon-carbon bonds with hydrogen.

reduction

hydrogenation 特指使用氢气的还原反应;reduction 更广义,指任何获得电子或降低氧化态的过程,不一定涉及氢气。

Hydrogenation is a type of reduction that specifically uses hydrogen gas.
