I am curious as to where i can buy Heptane in the UK. If anyone can help i'd very much appreciate it. I need it for a cleaner recrystallization. Thanks!

How/what would you re-xtalise with toluene?

Only place I know of where you can get heptane commercially is online from the states. I didn't shop around too much but if you google "bestine" that's all heptane there. It's sold for art supplies.

shipping's probably a kick in the nuts.

I just alter local solvents with acetone.

Thanks dude. Sorry about the mix up saying toluene... not sure why i did. I think i've been searching the properties of too many solvents.

It's ok... I'll get over it.

In time.

I found heptane online in the UK, but it is HPLC grade. Is that ok to use?

That's fine to use, but do they deal with private individuals? I'm guessing no because on the registration form the space marked "company" is mandatory.

I'd read this very carefully before committing to order from that site:

You are very right... crap

I wouldn't worry about it as it's not all that necassary. You can get your whites whiter than white with the leading high street brand. You'd pass the daz doorstep challenge anyways.

Although if you ask me, dirty spice is good spice. The more oils in the crystals the less sterile the experience.
For some reason with pure spice I have trouble remembering experiences.

yeah, you are right. It probably isn't all that necessary. I just wanted to see how the solvents differ. Thanks for the help.
