Simultaneous and direct measurement of gasndash;liquid density at high temperature and high pressure using the nuclearhyphen;spin projection method

摘要

A new technique to measure gasndash;liquid densities using the onehyphen;dimensional projection method is presented. The measurements were made in an NMR autoclave under highhyphen;temperature and highhyphen;pressure conditions. Some of the results of densities of cyclopentane determined from the room temperature to the supercritical regions are reported.
