A New Approach to the Combustion Calorimetry of Organosilicon Compounds. The Heats of Combustion and Formation of Hexamethyldisiloxane

摘要

A rotating-bomb method was developed for the precision combustion calorimetry of organosilicon compounds. The standard heat of combustion of hexamethyldisiloxane was determined, and a tentative value of the heat of formation was derived. An experimental method was found that may ultimately lead to improved values of the heat of formation of aqueous fluosilicic acid solutions. More reliable values of the heats of combustion and formation of benzotrifluoride were determined.
