Antoine constant of isooctane
Thread Content
Does anyone know the Antoni constant for isopentane, which is used in the Antoni equation to calculate saturated vapor pressure? Posts cannot be made in the resource request section; moderators may move them if they deem it inappropriate. This post was last edited by ghods on 2007-12-10 10:24]
I have here the values for n-heptane: A=15.8737, B=2911.32, C=-56.51. The units for the saturated vapor pressure are mmHg, and the temperature is in K. This post was last edited by furong4501 on 2007-12-10 11:36
There are several types of isooctane – could you be more specific? Do I need them all?
The unit for saturated vapor pressure is mmHg, and the temperature is expressed in K. For n-heptane: A=15.8737, B=2911.32, C= -56.51; for 2-methylhexane: A=15.8261, B=2845.06, C= -53.60; for 3-methylhexane: A=15.8133, B=2855.66, C= -53.93; for 2,2-dimethylpentane: A=15.6917, B=2740.15, C= -49.85; for 2,3-dimethylpentane: A=15.7815, B=2850.64, C= -51.33; for 2,4-dimethylpentane: A=15.7179, B=2744.78, C= -51.52; for 3,3-dimethylpentane: A=15.7190, B=2829.10, C= -47.83; for 3-ethylpentane: A=15.8317, B=2882.44, C= -53.26; for 2,2,3-trimethylbutane: A=15.6398, B=2764.40, C= -47.10. The effective Pvp value ranges from 10 to 1500 mmHg. That’s all I have, hehe; I think that’s about it. :lol Last edited by nanhua*aoyaoke on 2007-12-20 15:17 ]
May I ask in which book you found those constants? If you have the information, please provide the address.
