一:烃是什么意思(中英文)解释的意思
烃(hydrocarbon)是由碳和氢元素组成的有机化合物,是地球上最常见的化学物质之一。它们通常以分子式CnH2n+2表示,其中n为非负整数。烃可以分为两大类:饱和烃和不饱和烃。饱和烃是指所有碳原子都与四个单键氢原子相连,如甲烷(CH4);而不饱和烃则含有双键或三键,如乙烯(C2H4)和丙炔(C3H4)。它们具有多种用途,包括作为能源来源、工业原料、溶剂等。
Hydrocarbon (烃) is an organic compound composed of carbon and hydrogen atoms, and is one of the most common chemical substances on Earth. They are usually represented by the molecular formula CnH2n+2, where n is a non-negative integer. Hydrocarbons can be divided into two main categories: saturated hydrocarbons and unsaturated hydrocarbons. Saturated hydrocarbons have all carbon atoms bonded to four single-bonded hydrogen atoms, such as methane (CH4); while unsaturated hydrocarbons contain double or triple bonds, such as ethylene (C2H4) and acetylene (C3H4). They have various uses, including as a source of energy, industrial raw materials, solvents, etc.
烃的英文发音为/hʌɪdrəˌkɑːrbən/,其中“h”发音为清辅音/h/,“y”发音为元音/i/,“d”发音为清辅音/d/,“r”发音为浊辅音/r/,第二个“a”发音为元音/ɑː/,第三个“a”发音为清辅音/bən/。
烃是一种化学物质,可以作为能源、工业原料、溶剂等使用。它们在石油和天然气中广泛存在,并且也可以通过炼油和裂解等过程从这些资源中提取出来。此外,烃还可以通过化学合成的方法制备。
1. Crude oil is a mixture of different hydrocarbons, including alkanes, cycloalkanes, and aromatics.
原油是由不同的烃类混合而成的,包括脂环烷和芳香烴。
2. The main component of natural gas is methane, which is a simple hydrocarbon with one carbon atom and four hydrogen atoms.
天然气的主要成分是甲烷,它是一种简单的烃类化合物,含有一个碳原子和四个氢原子。
3. Ethylene is an important industrial raw material, which is mainly used to produce plastics and other chemicals.
乙烯是一种重要的工业原料,主要用于生产塑料和其他化学品。
4. Many organic solvents, such as benzene, toluene, and xylene, are also hydrocarbons.
许多有机溶剂,如苯、甲苯和二甲苯,也是烃类化合物。
5. The chemical formula of gasoline is usually written as C8H18, which means it contains eight carbon atoms and eighteen hydrogen atoms.
汽油的化学式通常写作C8H18,表示它含有八个碳原子和十八个氢原子。
烃的同义词包括碳氢化合物(carbon-hydrogen compound)、烷烃(alkane)、脂环烷(cycloalkane)、芳香烴(aromatic)等。它们都指由碳和氢元素组成的有机化合物。在不同的上下文中,可以使用不同的术语来描述这些化合物。
烃是由碳和氢元素组成的有机化合物,具有广泛的用途。它们可以作为能源、工业原料、溶剂等使用,并且存在于地球上最常见的化学物质之中。了解烃的定义、发音、用法以及常见的同义词,有助于我们更好地理解和使用这一重要的化学物质。
