Need advice converting fumarate to freebase...

[deeplake]

I ran out of freebase and tried to convert a 1/2 gm of my fumarate to freebase following a tek I seen on the wiki. I dissolved 500 mgs fumarate in 50 ml tap water. The ph of that was about 8. I then made a very concentrated mixture of water and sodium carbonate. I added it drop wise with stirring to the fumarate solution. It pretty much instantly started clouding up. I was'nt sure what I was supposed to get the ph to so I kept adding until it was around 12.
Then it sat for a few days. The liquid was clear and their were crystals so I thought all was well. Poured through a coffee filter, and the aproximately 50 mgs of crystals that ended up in the filter was all I ended up getting from it. I let the water dry out of the jar and added acetone to retrieve the crystals sticking to the sides and bottom. They did'nt seem to dissolve to well. Took a lot of shaking, and warmth. Then I poured it into a dish to evaporate. All I ended up with was this whiteish goo.
Could anyone tell me where I went wrong? Or better yet give me a link to a better tek for the conversion? Thanks.

Did you keep scrapping and rescrapping the goo, to see if it hardened up?

Did you throw away the water after filtering?

How clean were your fumarates?

What you can do is freeze and thaw the water and see if more crashes out, or add a bit of lye to the water and see if more crashes out.. Another option is, instead of doing the water conversion, to make a paste of dmt fumarate with calcium hydroxide or sodium carb and a bit of water, let dry, pull with acetone, evap.

I recommend whenever you try a new method, do a side-by-side, testing two different methods and seeing what works better for you. Also remember not to throw anything away because until you do, your DMT can always be recovered.

The goo actually ended up drying by today. Have'nt sampled yet.
And yes I kept the water. I will try your suggestion next time. Thanks.
