Sorry if I am making this confusing! I'll try to clarify exactly what I'm looking for. I do know what they are. They are 3-methyl-2-buten-1-ol (bp 143 C), 3-methyl-3-butenol-1-ol (bp 130 C) and 2-methyl-3-buten-2-ol (bp 99 C). The only published Henry's law constant is for 232 (65 atm-1). I may have said only 2 as 331 and 321 behave the same in my assays. The growth containers do have lids, but are not air-tight. I am asking the question because I am concerned that I cannot compare the 2 primary alcohols with the secondary alcohol with regards to their affect on cell growth at a particular concentration. They are all known volatiles emitted by various organisms. I guess a simpler question: how can I figure out their solubility?

Thanks for your questions. The systems are open--either as agar plates or liquid cultures. The alcohols are being added to aqueous solutions. There is no information as to whether as to whether they form azeotropic solutions. I would assume so, but wonder whether this would affect calculations much? They have reasonably high boiling points on their own (98, 130, 140 C) but are so stinky they must be volatilizing easily. The issue is that I want to compare the one with the lower boiling point with the two with higher bp.

I have two alcohols that have varying degress of volatility, I assume. I am using them as inhibitors of bacterial growth and in order to do a complete comparison, I need to determine what their actual concentrations are, i.e., what percent stays in solution and which is in gas phase. There are no published Henry's Law constants, thus I was hoping to determine this using only the boiling points. Any suggestions?
