Photocatalyzed oxidation of hydrocarbons in zeolite cages
http://pubs.acs.org/hotartcl/chemtech/96/jun/jun.html
The link is to a very interesting article about using zeolites (same thing as moleculcar sieves, I think) with O2 and visible light to oxidize various
hydrocarbons in a solventless reaction with very high selctivity and yields. I would be interested in trying a reaction of this sort, but have no
idea where to obtain the particular zeolite used in the article. They were using Zeolite Y. Anyone know a source for this stuff? Is it expensive?
It may be possible to use regular cheap molecular sieves like the ones used for drying alcohols and such, but I'm not really sure.
EDIT*** Looks like roamingnome already beat me to the punch on this one.

Very interesting! I dont know much about zeolites but I just might research them more.

mmm. Tectosilicates!
Zeolite ZSM-5 is used in the MTG (Mobile, Methanol To Gasoline) process. Check this out, it is quite cool; think Fisher-Tropsche, but more efficient.
Acid zeolites are good petrocracking and alkylation catalysts. Zeolites are also useful for performing selctive transformations (one end fits into the
cage, and the other is dangling out and reactive).

thanks for the article guy!
the preparation of a Barium exchanged zeolite seems pretty strait foward
sodium aluminate isnt too exspensive
buying some prepared zeolite Y seemed to come to around 100 bucks in the end....
even though i bet the oil industries must use like tons of the stuff......
its all about tapping into the right resource pool
the potenial for clean super reactions is there... when you trap the atom is does what you want....
