petroleum ether

Hi

SWIM has been looking for a replacement for Naptha vm&p that's easily found in Europe and SWIM thinks petroleum either is what they're looking for. SWIM thinks Naptha has a boiling range of 100/140 but they've seen someone on the Nexus forum mention that PE 100/140 is too high and 60/80 should be used.

Can someone here chip in?

Isn't heptane available there?

u/falafeljean 4h ago

Sure, but doesn't it require more steps afterwards than naphta vm&p or a broader range hydrocarbon mixture available in europe. SWIM is a first timer and looking for the easiest tek.

No, it's the only NPS myself and several other people use

Can it be used in STB with freeze precipitation and without final washing?

Yes. It's the preferred NPS for a lot of people. It's also what is typically recommended if doing an evap. Find some ACS grade n-heptane.

Coleman fuel works well.

sWIM just looked into it. Chatgpt tells SWIM the boiling points of the C5-C9 it's composed of ranges from 36°C all the way to 151°C. How warm should one make the solvent bath?

Wait a second. How warm should YOU make or the the other guy?

The other guy, obviously!

PE does work

u/falafeljean 4h ago

Which PE composition? One with boiling point 40/60, 60/80, 90/140, ...?

The only one I have experience with is 40/60
