Abstract: | 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. |
