Bonding studies of organometallic compounds of boron and the group IV elements. Part VII. Enthalpies of formation of hexamethyldisiloxane, hexamethyldisilane, and tetraethylsilane by rotating bomb calorimetry
Abstract
The enthalpies of formation of hexamethyldisiloxane (I), hexamethyldisilane (I), and tetraethylsilane (I) have been determined as –193·1 ± 4·9, –96·5 ± 1·7, and –66·4 ± 4·5 kcal mol–1 respectively, using rotating bomb calorimetry. The equipment used was a novel type of aneroid, vacuum-jacketted, rotating bomb calorimeter, details of which are given.
