A range of small, medium and large pore zeolite, and their modified fo
rms ave studied for their ability to separate di- from monobranched is
omers of hexane. he separation studies are carried out using high-temp
erature (250-350 degrees C) gas chromatography. Beta(H,Ba) is found to
be the most effective separator of 2,3-dimethylbutane and 3-methyl-pe
ntane and is therefore studied for its sorption capacities toward the
two hexane isomers.
