Factors Influencing Determing Molar Mass with Freezing Point Depression

BAI Yun-shan,WANG Jing-jie,TAO Wei-tong,LI Shi-rong(School of Chemistry and Materials Science,Shanxi Normal University,Xi'an 710062,China)  
The effects of preventing solidification temperature,water bath temperature,compensation electric current,stirring velocity and water content in cyclohexane on determining the molar mass of naphthalene in cyclohexane system were studied by using orthogonal experiment and self-developed NGD-02-type freezing point device.The results show that the above factors on the experiment follow the order of compensation electric current,preventing solidification temperature,water bath temperature and stirring rate.The optimum experimental conditions were obtained.The determination error of the naphthalene's molar mass is approximately 0.2%.Besides,water content in cyclohexane has no real influence on experimental results.
