摘　　要：利用C80型Calvet微量量热仪测定了对伞花烃+β-石竹烯,3-蒈烯+β-石竹烯和3-蒈烯+对伞花烃三个二元体系在298.15 K下的超额焓。三个二元体系的超额焓数据在全浓度范围内均为正值,并且最大值均在摩尔分数x1=0.5附近。采用Redlich-Kister方程对实验数据进行关联,标准偏差分别为0.2151、0.1773和0.4483 J·mol^(-1)。结果表明实验所测定的超额焓与关联结果吻合较好。在相同温度下,3-蒈烯+对伞花烃体系的超额焓值均大于含重质松节油组分的对伞花烃+β-石竹烯和3-蒈烯+β-石竹烯体系。The excess enthalpies of three binary systems（p-cymene ＋ β-caryophyllene, 3-carene ＋ β-caryophyllene and 3-carene ＋ p-cymene） were measured using a Calvet microcalorimeter（C80） at 298.15 K. The values measured were all positive under experimental concentrations, and the maximum values were found at the mole concentration x1 close to 0.5. The experimental data were correlated with Redlich-Kister equation and the standard deviations were 0.2151, 0.1773 and 0.4483 J？mol^（-1）, respectively. The results show that the excess enthalpies measured are in good agreement with the correlation results. The excess enthalpies of 3-carene ＋ p-cymene are larger than that of p-cymene ＋ β-caryophyllene and 3-carene ＋ β-caryophyllene containing heavy turpentine components under same temperatures.
