DPT freebase

[sunyata]

Does anyone know a simple procedure for converting DPT and other research chem's into freebase? Can you use the same technique as when making cocaine into rocks?

I have read procedures involving just the basic baking soda type
basification. They are supposedly possible but not very efficient. Here
is the more thorough procedure, from Erowid:



<div style="margin-left: 40px;">Conversion of Hcl salt to freebase:

2g of DPT Hcl was dissolved in 150ml of water. It was difficult to get
the crystals to go into solution and it required a small amount of
heat. Be careful not to apply too much heat, as DPT is very heat
sensitive. Once the DPT was in solution the water mixture was added to
a separatory funnel and ammonia hydroxide was then added dropwise to
basify. After each drop I swirled the mixture to distribute the ammonia
evenly, observing a white cloud of freebase forming out of solution.
When it reached a ph 8-9, I added 75ml of chloroform. This mixture was
swirled and thoroughly shaken for about 5-10 minutes with the
chloroform layer settling on the bottom. The chloroform extraction was
then poured off and saved in a flask. This process was repeated 3 more
times, with each extraction requiring additional ammonia hydroxide to
keep the ph level at 8-9. The last extraction was left to sit for 5
hours just to make sure that all of the DPT was recovered from the
water solution. The combined chloroform extractions were then
evaporated in a baking dish leaving a semi-clear-white DPT freebase oil
behind. 2g of finely ground dried parsley was added to the baking dish
and scraped and thoroughly mixed with a razor blade until the parsley
was completely saturated. The mixture was still somewhat sticky but
relatively easy to handle. It was then placed in a glass vial for easy
use and storage.</font></div>
