unsaturated hydrocarbons的意思是“不饱和烃”。具体来说：化学定义：不饱和烃是一类有机化合物，其分子结构中含有碳碳双键或碳碳三键等不饱和键。特性：由于存在不饱和键，不饱和烃在化学性质上比饱和烃更为活泼，容易发生加成反应、氧化反应等。分类：不饱和烃主要包括烯烃、炔烃以及含有其他类型不饱和键...

英文: In fact, unsaturated hydrocarbons, which are not usually present in virgin petroleum, are nearly always manufactured as intermediates during the various refining sequences.中文: 实际上,原油中一般不存在非饱和烃,几乎所有的非饱和烃都是在各种炼制过程中作为中间产品而产生的。
Unsaturated hydrocarbons are any hydrocarbon that have at least a single double or triple carbon-carbon bond. They can be linear, branched or cyclic. The main types of unsaturated hydrocarbons are: - Alkenes. Example: Ethene. - Alkynes. Example: Ethyne. - Aromatic Hydrocarbons. Example: Ben...
The class of unsaturated hydrocarbons also includes enins, CnH2n - 4,which contain a double bond and a triple bond, and polyenes. Unsaturated hydrocarbons of the aromatic series with general formula CnH2n- 6 have properties very different from those of more common hydrocarbons and therefore con...
