Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [7] Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).

2016年1月14日 · n-Hexane is a chemical made from crude oil. Pure n-Hexane is a colorless liquid with a slightly disagreeable odor. It is highly flammable, and its vapors can be explosive. Puren- Hexane is used in laboratories. Most of then- Hexane used in industry is mixed with similar chemicals called solvents.

1. 正己烷：分子结构为ch3-ch2-ch2-ch2-ch2-ch3，也被称为n-己烷或正戊烷。 2. 2-甲基戊烷：分子结构为ch3-ch2-ch(ch3)-ch2-ch3，其中甲基基团（ch3）位于碳链的第2个碳上。 3. 3-甲基戊烷：分子结构为ch3-ch(ch3)-ch2-ch2-ch3，其中甲基基团（ch3）位于碳链的第3个碳上。

Normal hexane (n-hexane) is both an anthropogenic and naturally occurring chemical. n-Hexane is a minor constituent of crude oil and natural gas. Its inclusion in a variety of petroleum products is a consequence of refining operations that separate hydrocarbons within specific ranges of boiling points for such uses as heating oils or automotive ...

2024年10月29日 · Hydrocarbons like n-pentane and n-heptane are used for the same purposes as n-hexane. However, 6-carbon molecules like n-hexane are notorious for their significant neurologic toxicity. The general aspects, anatomical considerations, natural history, and patterns of spread associated with n-hexane toxicity are explained below.
