【摘要】 <正> Menschutkin反应是研究得较多的亲核取代反应之一,对溶剂的动力学效应也进行了广泛和深入的研究,并获得了巨大的成功,但因溶剂对反应速率的影响因素众多,且又错综复杂,因此有些问题至今还不能了解得十分清楚,有些实验现象也难以解释,在以前的研究中,我们曾探讨了约二十余种溶剂对(1)、(2)两反应速率的影响更多还原

【Abstract】 The effects of methanol, ethanol, acetone, nitromathane, dimethylformamide, dimethyl sulfoxide and other above twenty solvents upon the rates for two Mens-chutkin’s reactions of triethylamine and benzyl chloride, pyridine and benzyl chloride have been investigated. The data obtained show that the solvation seems to have bearing the interaction between characteristic groups on the reaCtant molecules and those on solvent molecules.更多还原
