I'm doing my undergraduate research project on the title above. Basically what I have to do is to perform experiments on those 2 systems to get the VLE data.

Basically, the experiment is something like what's in the here  fulltext(2).pdf (161.63K)

I am wondering what type of column pack should I use for the GC. Any help would be nice.

Sounds like a fun and interesting project. I wish you success.

As for GC column. Considering the boiling points of those, I would think just about any column will be able to separate methanol from methyl oleate and water from methyl oleate. First resource I would point you to would be any of the chromatography supply companies (Supelco, Alltech, Restek, etc.). Their catalogs/websites usually have sample chromatograms for a wide variety of analyses (in this case, look for columns for fatty acid methyl esters or FAME's). It might even be worth a phone call to their tech support people and ask for a recommendation.

If this were my project, I'd be more concerned with the detector. Specifically, the ability of the detector to quantify low concentrations of the oleate. Except at the lowest methanol/water compositions, the oleate concentration in the vapor is going to be very low. Low to the point that I would be very worried about my ability to see and quantify reliably the oleate concentration. That's going to require some research to make sure you'll be able to quantify the oleate.

hey, thanks for the reply. it helped. yea, the detection part is tricky. but this is only proposal stage so, depending on the equipment my university could provide, there's still changes. right now is the equilibrium cell which we have is way too big. that's going to use alot of methyl oleate which is very expensive.
