Reaction heats of organic compounds. Part 5.—Heats of hydrogenation of dichloromethane, 1,1- and 1,2-dichloroethane and 1,2-dichloropropane

Abstract

Dichloromethane, 1,1-dichloroethane, 1,2-dichlorethane, and 1,2-dichloropropane were quantitatively hydrogenated to the corresponding alkane and the reaction heats measured at 250°C. Using appropriate heat capacity and heat of formation data, the heat of formation of these compounds at 25° has been estimated. An empirical equation which will reproduce the heats of formation of some mono- and dichloro-alkanes is given.
