用转动氧弹燃烧热量计测量了298.15K时2-氯丁烷和1,2-二氯丁烷的标准液态燃烧反应内能变化值,得到了它们的标准所态生成焓值,并进一步考查了二氯取代地氯代烷烃气态生成焓值的影响量.

关键词: 生成焓, 氯丁烷

The heats of combustion of 2-chlorobutane and 1,2-dichlorobutane were measured at 25?by using a rotation bomb calorimeter. The heats of formation in liquid and gaseous states were derived by using the experimental heat of sublimation determine by a vaporization calorimeter. The influence between the two chlorine atoms in the mol. on the heats of formations of 2-chloroalkanes is discussed.

Key words: ENTHALPY OF FORMATION
