采用动态法测定了全氟辛酸、全氟壬酸、全氟癸酸、全氟十一烷酸和全氟十二烷酸的蒸气压。测量在温度范围从（59.25至190.80）摄氏度的全氟辛酸，从（99.63至203.12）摄氏度，对于全氟壬酸，从（129.56至218.88）摄氏度，对于全氟癸酸，从对于全氟十一烷酸为（112.04至237.65）摄氏度，对于全氟十二烷酸为（127.58至247.36）摄氏度。全氟辛酸、全氟壬酸、全氟辛酸和全氟壬酸的压力分别为0.128 ~ 96.50 kPa、1.12 ~ 99.97 kPa、3.129 ~ 99 kPa。97)对于全氟癸酸为（0.616 - 99.97）kPa，对于全氟十一烷酸为（0.856 - 99.96）kPa。密封小瓶实验表明，全氟辛酸在室温下升华。
A dynamic method was used to determine the vapor pressures of perfluorooctanoic, -nonanoic, -decanoic, -undecanoic, and -dodecanoic acids. Measurements were made over the temperature range from (59.25 to 190.80) degrees C for perfluorooctanoic acid, from (99.63 to 203.12) degrees C for perfluorononanoic acid, from (129.56 to 218.88) degrees C for perfluorodecanoic acid, from (112.04 to 237.65) degrees C for perfluoroundecanoic acid, and from (127.58 to 247.36) degrees C for perfluorododecanoic acid. Pressures ranged from (0.128 to 96.50) kPa for perfluorooctanoic acid, from (1.12 to 99.97) kPa for perfluorononanoic acid, from (3.129 to 99. 97) kPa for perfluorodecanoic acid, from (0.616 to 99.97) kPa for perfluoroundecanoic acid, and from (0.856 to 99.96) kPa for perfluorododecanoic acid. A sealed vial experiment demonstrated that perfluorooctanoic acid sublimes at room temperature.
