And one of the sources of this chemical, xylene, is wood tar.

而这种化学物质——甲源之一木焦油。

Xylol, x-y-l-y-l, refers to a group of atoms that are derived from a clear, flammable liquid called xylene, x-y-l-e-n-e.

甲酚，x-y-l-y-l，指源自一种名为甲，x-y-l-e-n-e，清澈易燃液体一组子。

And that's how the chemical xylene got its name.

这就化学物质二甲名称由。

I'm looking in the Oxford English Dictionary, which gives the definition, the hypothetical radical C8H9 of xylene and its derivatives.

我在《牛津英语词典》中查找，这个词甲及其衍生物假设性基团C8H9。

And the really cool thing is that xylene comes from the ancient Greek word for wood, xylon.

而且真很酷，二甲这个词源于古希腊语中“木头”，即xylon。

It's from the same root as xylene and xylol and that's probably the coolest thing I know about xylol.

它与二甲和木醇同源，这大概我所知道关于木醇最酷事情了。
