Procurement of Heptane in Germany
Hi there,
I'm searching for a cheap source of ~30 l of heptane (preferably without toxic contaminants). Here in Germany it seems like you cant get those
flammable solvents anymore. It's the usual problem of suppliers not being willing to ship these "hazardous chemicals". So you either don't get it at
all or have to pay substantial amounts for a basic solvent.
The best I could find was this:
https://www.laboratoriumdiscounter.nl/de/heptan.html
Still the ADR shipping is expensive.
Thanks in advance for any help!

Any hazmat will cost more, but you have two options: go pick it up, or just pay the bill. Additional option is to compensate the shipping by ordering
more: if you will need it a lot, you can order 2, 3 or more canisters or even a barrel.
I pick up whenever possible. Ordering anything comes with flat rate 80€ up to one pallet domestic, which is dimes when doing a pallet of stuff, but
for one bottle or canister it's a bit on the hard side.

This may be an option for you as well: https://www.deoplosmiddelspecialist.nl/kopen/heptaan
Just send an email to them and ask what price they ask for shipping to Germany.
I myself have good experiences with this company. They have a limited assortment of chemicals, but what they have has a good price and most of the
chemicals they also sell to individuals. I, however, am in NL, shipping to Germany will be more expensive.

I believe that shipping between those two countries isn't a biggie. I didn't even notice crossing a border when I was driving around there with my
friend in Benelux, Germany and so on.

Thank you two for your answers and the seller tip!
I am still not to happy with the prices. I was just looking for "Waschbenzin" (should be petroleum ether in English?) and realized how much cheaper it
is. It is basically a Mixture of Pentane, Hexane and Heptane but sells for very low prices and on platforms like ebay with no extra shipping costs.
Shure it is not lab grade and the aromatic contents and other impurities can be quite high. Still I am considering it as an alternative for certain
tasks like crude extractions. I could therefor either use it as it is or distil of the tree main components. I have an old TCD GC standing around so I
should even be abled to check the purity after the distillation.

Waschbenzin sounds like white spirits, petroleum ether, mineral turpentine, and other names for the child. It's the stuff that is used in any general
thinner, solvent or cleaning application.
It is likely excellent extraction solvent, but if you intent to evaporate it off, you should first fractionate it, as higher boiling fractions can
boil pretty high. Extraction for other means, like acid-base, it works great, and is cheap and all over available.
While pure solvents are used in chemistry, many otc solvents can be used perfectly as is, and they can be order of magnitude cheaper.
