Hello all

Is there a single word or simple phrase that covers organic compounds that can exist in the gas phase, but that are not necessarily "volatile" in the sense of having a high vapour pressure ? Official methods separate "volatiles" from "semi-volatiles", but I am looking for a label for everything from small hydrocarbons to cholesterol and squalene, but excluding e.g. sugars, proteins etc that cannot exist in the gas phase (in air).

Over to you .......

volatilisable? It's a horrible word though

and you would get nit-picky editors squabbling over "s" or "z"

Peter

I see what you're looking for, but Idon't think there *is* such a word. We're talking about a continuously variable property (volatility). Think of things like density or hardness and you run into the same issues.

Tom, I think that you are right, unfortunately. How about in other languages, and then we can Anglicis/ze (or Americanis/ze) it. Surely there is an obscure eastern European language with the word vesehav in it, meaning very, semi and hardly volatile

It doesn't have to be one word, a snappy phrase would do it, or even (spirits forgive me) an acronym.

Peter

Another bad one?: Gaschromatographable.
Going from solid to gas/vapor has a word: sublimation.

Another bad one?: Gaschromatographable. Yes, a very bad one
Going from solid to gas/vapor has a word: sublimation.

And compounds that can sublime are called ..... ?

So what I am looking for is a combination of evaporatable and sublimatable.

Vaporizable ??

Peter

Vaporizable ??

That looks about as good as you're going to get.

How about fugacity

I had to look that one up - it does capture a substance's vapour pressure not being the only thing that detemrines its gas phase concentration, but it still does not distinguish between "vaporizable" and "non-vaporizable" substances. Would the adjective be "fugacious" ? - that has a kind of ring to it.

Peter

I thought fugacity was the ability to play Bach.

Quickly (speach) -siser of talant (story)
Vaporizated or volaturisated - is correct termine from describe substance properties "as see chemistry" . But in more langvigies the text is reducted to the minimum size suficient to understanding. From this perspective, the term "volatile" it seems to me => correct

Peter please use the word
'Fugacity' It is a better term to discribe volatility. Google it, and you will get thermodynamic education

No, its a bad termine.

Volature => летучие [letuchie] => Volature Correct translation. The meaning is clear in any language. "The fact that can fly (under these conditions)"
Volaturisated => ??? , Not translation, but the meaning is clear also.
Fugacity => фугативности [Fugativnosty] => fugacity Uncorrect translation (false transliteration) and meaning "dark as a nigger ass"/ Fung (ocide) (?) city(?) - it in English. In Russian - full nonsense, but a curse consonant (similar [Ni figa sebe] "Fack you, fantasic shit" ).

Interesting, whith corresponding Fung (丰) in Chinese ?!
