Write George Cody at the Geophysical Lab. He may still have some of the
original silicalite that Tom Hoering used back in the olden days.

Subject:  [ISOGEOCHEM] ZSM-5 and silicalite...

We want to remove n-alkanes from petroleum fractions using ZSM-5. However,
the information in the literature is a bit non-committal as to the specifics
of the zeolite and commonly used distributors. Can anyone send my any
information you might have as to specific vendors and specific ZSM-5 type?
Also, we are interested in acquiring some "silicalite" with 6A pore size.
This was a Union Carbide product and we cannot find a modern day distributor
in the continental US. HELP!!!
