Heats of sublimation of the triphenyl derivatives of boron, aluminium, gallium, and indium
Abstract
The molar heats of sublimation of the compounds Ph3M (M = B, Al, Ga, and In) have been determined by a gravimetric effusion technique. The values are 26·6 ± 0·3, 34·8 ± 0·6, 32·9 ± 0·9, and 33·6 ± 0·4 kcal. mole–1, respectively. Possible reasons for these high values are discussed.
