Ethylene Glycol 乙二醇

单词释义

1. 词性: 名词 (noun) + 名词 (noun)

   • 音标: /ˈeθəliːn ˈɡlaɪkɒl/ | 艾瑟林 格莱考
   • 中文释义: 乙二醇；防冻剂成分
   • 英文释义: A colorless, odorless, viscous liquid with the chemical formula C₂H₆O₂, commonly used as a solvent in paint strippers and wood finishes, also known for its antifreeze properties

2. 解释在木工领域中，这个单词的作用： Ethylene glycol在木工领域主要用作溶剂和添加剂。它常被添加到水性木器漆和清漆中，起到防冻、延缓干燥时间的作用，使涂料在低温环境下仍能正常使用。在某些脱漆剂配方中，乙二醇也作为溶剂成分，帮助软化和去除旧涂层。由于其毒性，使用时需要严格的安全防护。

3. 形态变化:

   • 复数形式: ethylene glycols
   • 化学分子式: C₂H₆O₂
   • 别名: 1,2-ethanediol

4. 词源故事: “Ethylene”源自希腊语”ethyl”（乙基）+ 后缀”-ene”（烯），”glycol”来自希腊语”glykys”（甜的）+ “alcohol”（醇）。1859年法国化学家Wurtz首次合成这种化合物时，发现它有甜味且属于醇类，于是用这个名称。就像木工师傅根据木材特性给它们命名一样，化学家们也根据物质的性质来命名化合物。

木工小故事

Chemist Maria studied various glycol compounds for safer wood treatments. The ethylene bonds were crucial for solvent properties, but polyethylene alternatives might be safer. Her glycolic acid research showed promise for eco-friendly strippers. The ethylenic structure provided excellent penetration, yet toxicity remained a concern. Maria hoped her glycol-free formulations would revolutionize wood finishing, making workshops safer while maintaining the quality craftsmen demanded.
