摘要：
A slightly modified Burnett apparatus has been used to measure 32 vapor-pressure data for HFC-32 in the temperature range from 273.39 to 347.29 K. The uncertainties of temperature and pressure are estimated to be within +/-10 mK and +/-500 Pa, respectively. The purity of the sample used in this work is 99.95%. On the basis of our data and of data from the literature, a vapor-pressure equation for HFC-32 is also proposed.
