…There are saturated cycloalkanes without multiple bonds and unsaturated cycloalkanes with multiple bonds, but both have reactivity that is significantly different from aromatic compounds, and are therefore distinguished from them. Saturated monocyclic cycloalkanes are called cycloparaffins (e), and are obtained by fractional distillation of petroleum. The simplest is the three-membered cyclopropane C 3 H 6 , followed by cyclobutane C 4 H 8 , cyclopentane C 5 H 10 , cyclohexane C 6 H 12 , and so on. … *Some of the terminology explanations that mention "cycloparaffin (e)" are listed below.

…多重結合を含まない飽和のものも,また多重結合を含む不飽和のものもあるが,どちらもその反応性が芳香族化合物とは著しく異なるので,これと区別される。飽和の単環式のものは,シクロアルカンcycloalkaneあるいはシクロパラフィンcycloparaffin(e),シクロパラフィン系炭化水素といい,石油の分留によって得られる。最も簡単なものは3員環のシクロプロパンC3H6であり,以下シクロブタンC4H8,シクロペンタンC5H10,シクロヘキサンC6H12,……と続く。… ※「cycloparaffin(e)」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
