文摘

Critical temperature, critical pressure, and vapor pressure measurements have been performed on three compoundsby a flow method with ultralow residence times. These compounds are as follows: 1,6-hexanediol, 1,3-benzenediol,and piperazine. Accurate vapor pressure data are also included for 1,2-benzenediol, but this compound provedtoo unstable to directly determine the critical constants using this apparatus.
