?一:烴是什么意思(中英文)解釋的意思
烴(hydrocarbon)是由碳和氫元素組成的有機(jī)化合物,是地球上最常見(jiàn)的化學(xué)物質(zhì)之一。它們通常以分子式CnH2n+2表示,其中n為非負(fù)整數(shù)。烴可以分為兩大類:飽和烴和不飽和烴。飽和烴是指所有碳原子都與四個(gè)單鍵氫原子相連,如甲烷(CH4);而不飽和烴則含有雙鍵或三鍵,如乙烯(C2H4)和丙炔(C3H4)。它們具有多種用途,包括作為能源來(lái)源、工業(yè)原料、溶劑等。
Hydrocarbon (烴) 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.
烴的英文發(fā)音為/h??dr??kɑ?rb?n/,其中“h”發(fā)音為清輔音/h/,“y”發(fā)音為元音/i/,“d”發(fā)音為清輔音/d/,“r”發(fā)音為濁輔音/r/,第二個(gè)“a”發(fā)音為元音/ɑ?/,第三個(gè)“a”發(fā)音為清輔音/b?n/。
烴是一種化學(xué)物質(zhì),可以作為能源、工業(yè)原料、溶劑等使用。它們?cè)谑秃吞烊粴庵袕V泛存在,并且也可以通過(guò)煉油和裂解等過(guò)程從這些資源中提取出來(lái)。此外,烴還可以通過(guò)化學(xué)合成的方法制備。
1. Crude oil is a mixture of different hydrocarbons, including alkanes, cycloalkanes, and aromatics.
原油是由不同的烴類混合而成的,包括脂環(huán)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.
天然氣的主要成分是甲烷,它是一種簡(jiǎn)單的烴類化合物,含有一個(gè)碳原子和四個(gè)氫原子。
3. Ethylene is an important industrial raw material, which is mainly used to produce plastics and other chemicals.
乙烯是一種重要的工業(yè)原料,主要用于生產(chǎn)塑料和其他化學(xué)品。
4. Many organic solvents, such as benzene, toluene, and xylene, are also hydrocarbons.
許多有機(jī)溶劑,如苯、甲苯和二甲苯,也是烴類化合物。
5. The chemical formula of gasoline is usually written as C8H18, which means it contains eight carbon atoms and eighteen hydrogen atoms.
汽油的化學(xué)式通常寫作C8H18,表示它含有八個(gè)碳原子和十八個(gè)氫原子。
烴的同義詞包括碳?xì)浠衔铮╟arbon-hydrogen compound)、烷烴(alkane)、脂環(huán)烷(cycloalkane)、芳香烴(aromatic)等。它們都指由碳和氫元素組成的有機(jī)化合物。在不同的上下文中,可以使用不同的術(shù)語(yǔ)來(lái)描述這些化合物。
烴是由碳和氫元素組成的有機(jī)化合物,具有廣泛的用途。它們可以作為能源、工業(yè)原料、溶劑等使用,并且存在于地球上最常見(jiàn)的化學(xué)物質(zhì)之中。了解烴的定義、發(fā)音、用法以及常見(jiàn)的同義詞,有助于我們更好地理解和使用這一重要的化學(xué)物質(zhì)。
