Résumé :

The contraction of density globes on evacuation has been investigated in connection with a physicochemical examination of easily liquefied saturated hydrocarbons. A hydrostatic method of measurement has been applied to the problem, as well as the method of Travers; the results by both methods are in good agreement. The empirical equation proposed by Moles and Miravalles for the calculation of the compressibility of density globes is given additional confirmation by the results of the measurements. Data have been obtained which lend support to the hypothesis that the contraction of density globes is a linear function of the pressure difference to which the bulb is submitted. © 1929, American Chemical Society.
