【摘要】 对影响乙醇-环己烷系统ε12-w2关系线性的因素进行了研究。结果表明,溶液浓度是影响的主要因素。室温下,w2(质量分数)为0~0.076时,ε12-w2关系为线性;测得乙醇分子偶极矩与文献值相对偏差低于3.0。更多还原

【Abstract】 A research was done about influence on linear ε 12- w 2 relation of ethanol-cyclohexane solution. The experiment result confirmed that concentration of the solution had the main effect on linear ε 12- w 2 relation of ethanol-cyclohexane solution. The ε 12-w 2 relation was linear when the mass fraction of ethanol in solution was lower than 0. 076 at room temperature. The relative deviation between experiment value and review value for dipole of ethanol molecule was lower than 3. 0.更多还原
