Sorry, Dick, there might be some benzine in kerosene, but it would be an
impurity. Benzine is a low molecular weight (meaning it's lighter and more
volatile) aliphatic hydrocarbon that is the main constituent in the mixture we
call gasoline (and the British call petrol). Kerosene is a mixture of higher
molecular weight hydrocarbons, which makes it slightly viscous (oily). When the
oil producers separate the ingredients in crude oil (if you can visualize this)
the highest hydrocarbons are wax (or asphalt in some low-grade crude), then
lubricant grade, followed by diesel fuel (very similar to kerosene), kerosene,
and then the low molecular weight constituents that make up the various
combinations of gasoline. Benzine is purified from the gasoline part.

This all has an interesting history, but hardly altphoto, so I won't go into
it.
