Abstract
A rotating-bomb method was developed for precision combustion calorimetry of organic chlorine compounds. The heat of combustion of 2,3,5,6-tetrachloro-p-xylene was determined. Two reducing agents, hydrazine dihydrochloride and arsenious oxide, were used to reduce the free chlorine produced in the combustion reaction to chloride ion. Arsenious oxide proved to be the superior reducing agent. The heat of formation of tetrachloro-p-xylene from graphite and gaseous hydrogen and chlorine was found to be -42.0/sub 6/ kcal. mole/sup -1/.
