General description

Pentane (n-pentane) undergoes hydroisomerization in the presence of a nanocrystalline beta (BEA) zeolite. It isomerizes to iso-pentane in the presence of ZSM-5 (Zeolite Socony Mobil-5) zeolite catalysts under hydrogen and nitrogen atmosphere. Platinum catalysts when supported on sulfated zirconia-based solid superacids, promotes chemisorption and effective combustion of pentane.

Application

Pentane may be used for the fabrication of planar lipid bilayers on the films of amorphous PTFE (PTFE) by the “painting technique”.
Pentane may be used in the preparation of n-hexanal via photo-catalyzed carbonylation of the terminal methyl group in the presence of a rhodium catalyst.
