溶液法测定分子偶极矩是物理化学实验中最基本的实验之一,多数高校采用复旦大学所编的电容电桥法[1]进行测量。但从历届学生实验来看,学生反映实验不但工作量大并且作图繁多,不易为学生所接受。其次大量使用有毒性的苯,无法在通风橱内进行操作。因此,我们尝试用环已烷代替苯作溶剂,便于改善实验环境。众所周知偶极矩的测定与温度有关,故必须在恒温条件下进行。但当使用CC—6型 The solution dipole moment method is one of the most basic experiments in physical chemistry experiment. Most colleges use the capacitance bridge method [1] made by Fudan University. However, from the previous student experiments, students reflect the experiment is not only heavy workload and a variety of mapping, not easy for students to accept. Followed by extensive use of toxic benzene, can not be operated in a fume hood. Therefore, we try to use cyclohexane instead of benzene as a solvent, to facilitate the improvement of the experimental environment. It is well-known that the determination of dipole moment is related to temperature, so it must be carried out under constant temperature. But when using the CC-6 type
