Title: Antoine Constants
Post by: ShaiGuy on September 19, 2003, 02:04:00 AM

I was wondering if anyone knew of any good online table of Antoine constants. I'm looking for the constants of BDO (1,4-butanediol, GBL(gamma-butyrolactone)and GHB. Many Thanks,
ShaiGuy

The NIST Chemistry Webbook contains Antoine's equation coefficients for the vapor pressure of many chemical compounds

BDO....

There are also a couple of interesting sites on the subject and some background on vapor pressure and the reason for the coefficient and values for most compounds.....java
