Benzin/Benzene

froot - 3-8-2004 at 13:27

I have doubts about Benzin being C6H6 which I can find in almost any store here. I've found MSDS's saying it's the same thing and others saying the one is coal naptha and the other petroleum naptha. But petroleum is derived from coal?!?

Could somebody please help me with the similarities or differences between the 2?

Hmm. "Benzin" sounds awfully close to the Swedish word "bensin" and identical to the German word "Benzin", both meaning "petrol" (BE) or "gasoline" (AE). That would make "Benzin" mostly octane, whereas benzene is C6H6, a characteristically cyclical hydrocarbon, not the same thing at all.

Benzin is commonly referred to as petrol or gasoline. It's a mixture of hydrocarbons, IIRC the second highest boiling fraction of crude oil.

It contains mostly alkanes (C6 - C8) and some aromatic hydrocarbons like toluene, xylene and benzene. Higher octane fuels contain a larger percentage of aromatic hydrocarbons.
