【摘要】 溶液法测定分子偶极矩的研究体系应选择低毒或无毒的溶液作实验试剂,如正丁醇-环己烷体系;实验条件中恒温装置可略去,在室温下操作即可。密度的测定也可根据不同的要求简化测定仪器和实验过程;本文介绍了两种试剂的循环利用方法,力求实现一个环境友好、方法简捷、条件简易的实验教学过程。更多还原

【Abstract】 The low-toxic or non-toxic reagent,such as n-Butanol-cyclohexane should be selected for the research system of dipole moment measure with solution method.Constant temperature equipment may be omitted,that is,operated at room temperature,in experimental conditions;Apparatus and experimental procedure for the determination of density also may be predigested according to different requirements,Two types of recycling utilization methods for reagents are introduced,which will incorporate experimental teaching procedure an environment-friendly,easy methods and simple conditions-simple.更多还原
