Hello, my friend was planning on doing an extraction and then VM&P naphtha got banned from where we live. I know that we could use zippo lighter fluid as well as a few other chemicals for the extraction but we aren't sure how much to use. Could you guys tell me what you think the next best alternative would be to VM&P and how much we should use for ~100g of MHRB

Be careful what brand and product you buy (solvent), not all lighter fluid works, check the MSDS and try asking/checking around to see if it's safe, most people on this site would be glad to keep another member alive

The amount shouldn't change when dealing with the solvent, the lye isn't too hard to find, look for drain cleaners that are in powder/crystal form, and check that they are ONE HUNDRED PERCENT sodium hydroxide (lye). If they are only say, 95%, you're smoking/intaking residues and potentially chemicals that can eat away at you (hey, they were meant to go down the drain!). Drano has no products that are 100% lye, look out for rootol (mis-spelling?)

If the lye/acid is not already pre-measured in the teks, look into pH, and pH papers to measure how much lye or acids to use.

Yeah, the lye was easy to find like you said. I'm just looking for a good alternative to the naphtha.

Can you get Heptane (sold as Bestine, a rubber cement remover in the u.s.)? Try an art supply store.

Ok thanks, I'll try to find some. How much do you think I should use for approx 100g of MHRB?

Just look in the Wiki above...choose an extraction tek, and it will specify the required quantities for you.

I have looked at many teks, but many call for the use of naphtha. I can't find one for heptane. But are you trying to say that 250-400ml of naphtha will be the same as 250-400ml of heptane or some other chemical?
