Just did a small evap test on some ronsonol, would you still use it

Looks like harmless C9 hydrocarbons that don't evaporate. Convert your freebase into fumarate and dissolve it in water. Siphon off the oily layer and evaporate the water.

Edit: the C9 hydrocarbons might even dissolve in the acetone during the FASA step, so alot of it is already washed.

Ha you've lost me ufostrahlen, what exactly would I need to do, what do you suggest I use instead of ronsonol, thanks for the reply

You can use it with an A/B tek and a FASA tek. Wash the fumarate with water at the end (the paraffins won't dissolve in water and will swim at the top). Or switch to D-limonene.

Basically follow the DMT Handbook (don't mix Naphta with plastic, always use glass) or Cyb's tek, then DMT FB to fumarate via the FASA tek, once you've obtained the DMT fumarate, dissolve it in water and siphon off the paraffins. Let the water evaporate. Tada!

I find this interesting as a couple months back I did an evap test with Rosonol and it came up clean....now I am feeling sketched out about using it.....

I'm about to buy some heptane or petroleum ether 40 - 80 instead only got a few cans of ronsonol left, which would i be best off getting, never done the fasa or worked with D-limonene, I do cybs/earthwalkers tek and been successful so don't really want to change. Thanks

Yeah so did I, but someone mentioned today that's it's been changed so I checked and thought I'd post the pic to see what people think

̶h̶̶e̶̶p̶̶t̶̶a̶̶n̶̶e̶̶ ̶ pentane is of course the gold standard. You can also use the FASA as an intermediary step for washing and convert back to freebase.

Cheers ufostrahlen looks like heptane it is also I've never seen the dmt handbook there's some good info in there thanks, do you think it's worth doing the a/b tek or will I be better off sticking to cybs and freezing and thawing my bark or powdering it, can only get shredded mhrb. thanks

Yw. They both work, so it's a personal preference. Read both and decide for yourself. Some materials are more accessible in different countries, so that's a criteria, too.

Cheers for you help im in the uk so will have to have a look, just one last question regarding the heptane, it's 95% heptane is that the one I want

Just to say, if you wish to use petroleum ether sometimes, use 40-60 °C. It works like a charm, I know because I'm still using it with great results.

petroleum ether = 90% n-pentane with some n-hexane

All 3 solvents are fine and share similar properties.

Cheers ufostrahlen and oversoul1919

You want something like this:

http://apcpure.co.uk/pro...59/petroleum_ether_40_60

Their website has lots of different solvents as well:

Yeah that's the one which would you choose out of the 95% heptane or the petroleum ether

I'm sorry, I meant Pentane (C5), not Heptane (C7). But the 40/60 PE still looks like the better deal due to the low BP (lower = better), so the initial eBay url is still valid. Make an evapo test nevertheless.

Cheers think im gonna go with the heptane

Bad idea, heptane (C7) has a BP of 98°C.



You want a C5-C6 mixture like PE, which BP is 40-60°C at the max. Otherwise you will have C7 hydrocarbons that don't evaporate. Your room temperature is max. 30°C and the BP of DMT fb is 45°C. Just do the math and don't forget to read the MSDS and specifications of the solvents:
