METHODS The hydroxyl groups of magnolol were protected using ketol reaction and the products were purified by recrystallization from hexane.
方法厚朴酚两羟基用缩酮保护,再用正己烷重结晶分离纯。
The perservative in liquid beverage was extrcated with n-hexane.The hexane layer was subjected to cyclodextrine polymer resin colume.The colume was eluted with aqueous solution of ethanol.
用正己烷萃取液体饮料中的防腐剂,使萃取液经环糊树脂分离后,用乙醇溶液洗脱。

Consider this molecule, a hexane with a benzene ring attached to carbon number 2.
考虑这个分子, 一个苯环连接到碳数 2 的己烷。
Sometimes, a hexane can look like a pentane with an ethane sticking off of it.
有时,己烷看起像戊烷, 上面烷。
But pentane, C5H12, has 3 possible isomers and C6H14, known as hexane, has 5.
但是戊烷 C5H12 有 3 种可能的异构体, 而称为己烷的 C6H14 有 5 种。
Ketones, add '-one', so a ketone of a hexane would be hexanone, and amines, you just add '-amine' to the end so methenamine or propanamine.
酮,添加“-one” ,所以己烷的酮就是己酮,而胺,你只需在末尾添加“-胺” ,所以甲胺或丙胺。
