Struggling getting naphtha uk

[dustyforge]

Hi there I'm going to do my first extraction. I've got all the bits I need but struggling to find naphtha in the uk. I've hound this product and was wondering if anyone could please tell me if this is the correct stuff (I was a bit thrown by the hydrotreated light sbp 3 bit)

Hi there and welcome to the Nexus!

That product would likely do the job. Just make sure it evaporates cleanly - it should do, it seems to be a brake cleaning fluid.

"Hydrotreated" refers to a standard purification process for a whole lot of hydrocarbon solvents. You'll also see the term if you look closely at any bottle of white spirit or "turpentine substitute". I strongly suspect that "SBP 3" refers to a standard for boiling point which you may find reference to if you look at the documentation (SDS). It would be wise to make sure that this value lies below 98°C (a boiling range of 80 110°C would probably be OK).

The other thing to make sure of is that it contains <5% aromatics, otherwise freeze precipitation might not work.

There are various OTC petroleum distillates available in the UK if you know where to look for them, although they may have been getting harder to find lately.

OK, I have to admit, the technical data on that MSDS is pretty lame!

9.1. Information on basic physical and chemical properties

Many thanks for the reply. Are there any uk products you might be able to recommend?

Zippo (other brands are available) lighter fluid is available literally everywhere, and is what a lot of people use. Heptane is so simple to find (20 odd quid a litre delivered to my door) it hurts my head to see threads like this.

Yes, that's the thing - there's a whole load of synonyms for naphtha/petroleum distillates. I've posted about that subject so many times now, it would be easier just to put a link in my sig.

The search function will likely return a hefty amount of results for "uk naphtha".
