请高手解答有关文献的翻译问题? “5 g (98 mmol) of a Na dispersion in paraffin was placed in a three-necked flask under nitrogen and treated with 20 mL toluene. The solvent was removed with a syringe and 4.50 g (43 mmol) of 2,6-lutidine in 40 mL dry THF was added.” 首先,文中所指的 “Na dispersion in paraffin ”是指什么,有谁用过? 此外,用toluene处理是什么意思?如何操作?目的何在? 最后,“The solvent was removed”指仅仅除掉toluene还是又包括了paraffin? 谢谢大家的帮助和指导!查看更多4个回答 . 3人已关注
