Distilling OLD UK petrol
I have a can of old petrol (18 months) thats half full and used for the lawnmower, the smell is much diminished so alot of the high volatile stuff
seems to have gone.
I was wondering about distilling the petrol, seeing as its old I am thinking it might be a bit safer, however the boiling points would probably be
mostly higher now.
What I would like to know is what is likely to be left in old petrol (would it be Alkenes etc or what), and the likely boiling points. I would like to
get fractions around 50c and up
sorry if its a dopey question
Dont ask me, I only know enough to be dangerous

I suspect that the various fractions remaining would have close boiling points,
so unless you have got a VERY good fractionating column
I doubt that you could collect pure fractions.

There is still some low fractions around 27C, I have also collected some at 40c and had to stop for the day due to a stupidity moment.

Gasoline (petrol as they say in England) is a very complex mixture. I have done fractional distillation on it. The temperature goes up at 33 C, for a
while you get a liquid, then it goes up a little and stops, and it continues like that. I don't have advanced equipment to know what exactly the
compounds were.
Composition also varies from summer to winter and from different companies.
Anyway, here is an attachement gasolinecomp.pdf.
It contains a list of compounds in some sample.

We must attach the electrodes of knowledge to the nipples of ignorance and give a few good jolts.
Yes my evolutionary friends. We are all homos here. |
