Saturated vapor pressure of triphenylphosphine
Thread Content
Those who have information on the saturated vapor pressure of triphenylphosphine at temperatures of 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, and 80 degrees, please share it. Thank you!
10 degrees – 2*10-7 KPa, 20 degrees – 6.5*10-7 KPa, 30 degrees – 2*10-6 KPa, 40 degrees – 7.2*10-6 KPa, 50 degrees – 2*10-5 KPa, 60 degrees – 5.7*10-5 KPa, 70 degrees – 2*10-4 KPa, 80 degrees – 3.5*10-3 KPa.
Triphenylphosphine is a solid at temperatures below 81°C; how can there be a concept of saturated vapor pressure? A saturated vapor pressure exists only when it is in a liquid state and below the critical temperature. In other words, a saturated vapor pressure can exist only at temperatures between 81.25~734.85°C.
:Lol, it’s actually the manufacturers who don’t understand this and want to find out… :lol:lol
