【摘要】 首先用RD 496-Ⅲ型微量量热计测定了环己烷+正己烷和(s)-(-)-柠檬烯+β-蒎烯体系在298.15 K下的超额焓,实验结果与文献值吻合,同时实验数据采用R ed lich-K ister方程进行关联,标准误差分别为1.3 J.m o-l 1和0.6 J.m o-l 1,表明该量热计用于测定松节油体系的超额焓数据是可靠的.其次,实验测定了β-蒎烯+对伞花烃体系在2 9 8.1 5K下的超额焓,用R ed lich-K ister方程对实验数据进行关联,标准误差为0.5 J.m o-l 1,该二元体系超额焓数据为首次报道.更多还原

【Abstract】 The excess enthalpies for two binary systems of cyclohexane+n-hexane and（s）-（-）-limonene-pinene were measured at 298.15K by RD496-Ⅲ microcalorimeter and correlated by Redlich-Kister equation,the standard deviations were 1.3 J·mol^-1 and 0.6 J·mol^-1,respectively.The experiment results are in good agreement with that of the reference.It shows that the experimental excess enthalpies of turpentine oil system could be measured by RD496-Ⅲ microcalorimeter.Then the excess enthalpies for binary system of β-pinene+p-cymene were measured by RD496-Ⅲ microcalorimeter at 298.15 K and correlated by the Redlich-Kister equation, the standard deviations was 0.5 J·mol^-1.The excess enthalpy data for this system was firstly reported.更多还原
