Book Description
Briefly, the methods of determining low vapor pressures have been reviewed. Emphasis has been placed on molecular effusion, including a theoretical discussion and the subsequent application of molecular beams to the determination of vapor pressure. The problems met in the preparation, purification and handling of anhydrous zirconium tetrachloride have been discussed. Vapor pressure measurements on zirconium tetrachloride have been made over a temperature range of fifty degrees, 70 deg C. to 120 deg C, . and the mean molar heat of sublimation for this temperature range has been calculated. The value of 20.3 kcal per mole obtained is not unreasonable in view of the fact that values for the same quantity determined by other investigators in the temperature range of 239 deg C. to 346 deg C. is reported to be 24.4 kcal. per mole.
