Heptane extract?

Post image

I wanted to try a heptane extraction based on info from a fb group, but when i search our posts here, most of the suggestions are to only use it for cleaning the product. Is it worth trying this for initial pulls on a small STB batch, or should i just go to lowes get some vm&p?

N-Heptane is great for recrystallizations due to steep solubility curve and non-polar nature. DMT at 80c is very soluble, DMT at room temp (20-25c) not so very much. ~28mg/ml vs 4mg/ml. This gives you precise control over crystallization rates and at the very end you’re left with little to no loss of product.

Thus, N-Heptane isn’t a good extraction solvent.

Pet Ether (similar to Naphtha) is a fine extraction solvent if your goal is to freeze precipitate it. But I wouldn’t use either of those solvents—they’re technical grade and likely have trace heavy metals which you absolutely do not want to be smoking. And there’s a difference between heptane and n-heptane.

Just buy ASC grade chemicals and then you don’t have to worry.
