composition of benzin
Anyone know where I can find a listing of the percentages of the components of benzin (vm&p naphtha). I'm wondering mainly how much hexane. I was
thinking it might be cheaper to just distill hexane from naphtha than to buy it from chem companies.

with all do respect( and unless benzene here is used as slang for standard Gasoline) if the goal is cheaper Hexane wouldn't fractional distillation
suffice? As far as listing I'd call the maker for an MSDS on the product you are trying to use..that may or may not work. Short of all that there are
a few members here with chromatography machines that would do very well if you sent them a sample.

So did I, just now. Took two minutes, if that. Searched on the CAS # of the
first MSDS. Second link was http://www.cdc.gov/niosh/npg/npgd0664.html. On that page: | Quote: | | VM&P Naphtha is a refined petroleum solvent predominantly C7-C11 which is typically 55% paraffins, 30% monocycloparaffins, 2% dicycloparaffins
& 12% alklybenzenes. |
So, how much hexane do you expect from this?
You could have ascertained this from looking at the boiling point on the MSDS and looking up the boiling point of hexane.

If you did that and actually read what naphtha is you would see that it is a mixture, and there is no specific ratio of ingredients, however there are
different grades of petroleum ether taken at different distillation fractions, (60/80, 30/40, etc.). Look into the 60/80 petroleum ether. There, was
that enough info for you?
