which shipping method? Are you in the US?

Standard hazmat shipping is about paperwork, labeling, packaging, and insurance. The standard courier van will pull up to your house and drop off a standard looking box, just as they would with any other shipment. The only difference on the outside of the box may be some additional labeling, varying depending on what is inside, and in what quantity.

No, there won't be a suspicious looking van, nor will your neighbors see a team of men in Tyvek chem suits walking your THF to the door.

If the quantity is small enough it won't even need the standard external paperwork under ORM-D classification or a limited quantity exemption.

Basically, you're paying for the packaging, paperwork, and red tape. This would be the case if you were ordering anything from canned air, to ammo, to large amounts of perfume, or even 151 proof alcohol.

buy pvc solvent cement lookup the msds on that mostly thf.
better remove all those peroxides before you distill, it likes to go BOOM!

which peroxides?

i only recall MEK and THF in the pvc cement

Maybe i was looking at a thinning agent, in which case that might be something to look for..

there you go!!

That is a mad source for thf

(cyclohexanone in thier too) wernt u looking for that also?


when a 2L thing of glue rocks up no one will care, as opposed to a HAZMAT team delivering THF in full suits

Yes, the distillation will yield good separation.  If you do it slow you won't need a column.  Make sure your receiving flask is in a ice water as THF has a high vapor pressure at STP (albeit not as ridiculous as ether).  Distillation of THF isn't as dangerous as you'd think, just apply common sense.  Here's a quote from SM on distilling THF from various OTC's, apparently they recommend adding BHT as copper wire does not seem to be effective at prevent peroxide formation:

i find distilling from the can it came in is always the most convenient for glues and paint strippers. It doesn't mean you'll get a decent fractionation or anything but you have something which you can conveniently use in your glassware to further resolve.

As a general rule remove 1/3 of the can contents, spike a hose from the can to your condenser, immerse can in water and heat water electrically. Very sophisticated, when sufficient distillation has occurred pour in remaining 1/3 of starting material and distill to completion.
Throw away can responsibly (or burn it!!)

I'll take a look at my bottle and let you know what it says next time I'm in the lab.  It's reagent grade, I feel like its 500ppm but I'm not sure.
