STANDARD MOLAR ENTHALPIES OF FORMATION OF 9 FLUORINATED BETA-DIKETONES BY ROTATING BOMB CALORIMETRY

The standard enthalpies of formation of the following fluorinated beta -diketones at T = 298.15 K were determined from their enthalpies of co mbustion measured using rotating bomb calorimetry. [GRAPHICS] With ent halpies of vaporization and sublimation, the enthalpies of formation o f these beta-diketones were derived for the gaseous state in their eno l and keto forms. Where applicable, the enthalpies of formation in the gaseous state correlated satisfactorily with values estimated by grou p additivity methods. (C) 1997 Academic Press Limited.
