研究人员使用的方法是将咖啡渣隔夜使其干燥,然后放入一些常见的化学溶剂中,例如正己烷、乙醚和二氯甲烷,来溶解咖啡渣中的油类成分。
The researchers start off by drying their coffee grounds overnight and then pour in some common chemical solvents, such as hexane, ether and dichloromethane, to dissolve the oils.
例如苦味的抗疟疾药奎宁和氯奎宁,都使肌肉细胞放松。
The bitter antimalarial drugs quinine and chloroquine, for example, relaxed the muscle cells.
例如有机锡的稳定剂可以和羧甲基纤维素分子的不稳定氯原子配位结合,有机锡和不稳定的氯原子发生置换反应。
For example, the stabilizer of organotin compounds can be combined with the unstable chlorine atom of the carboxymethyl cellulose molecule, and the organotin and unstable chlorine atoms are replaced.
金属M例如可通过熔盐电解从其氯中回收,并循环到该工艺的第一步。
Metal m can be retrieved from its chlorine, e. g. by molten salt electrolysis, and recycled to the first step of the process.
