I'll try to explain the method in layman's terms as I understand it... The highest lvl of chemistry education I have is highschool but I've read all the posts and have done much research as well... so here goes:
(
Any suggestions, modifications, or corrections to the following method would be much appreciated.)
Ingredients needed (which can all be purchased online on various websites):
154.7g pure GABA, 103.5g Sodium Nitrite, 225.2g Sulfuric acid, 750ml DCM, 90.1g baking soda (or Sodium Hydroxide, not sure on exact amount though) and Distilled water.
Equipment needed (All of which can also be purchased online):
high temp thermometer (at least 210c max temp), 1 1L capacity, flat bottom Erlenmeyer flask, 1 distilling set up, 1, 1L capacity seperatory funnel (for the separation process and the acid dropping process), 1 Bunsen burner or similar heating apparatus (a propane torch maybe?) one large bowl (at least 3L capacity), PH testing strips, and safety equipment (i.e. safety goggles, gloves, apron).
PROCESS:
1: In the 1L Erlenmeyer flask, mix the GABA, Sodium Nitrite, and 750ml water.
2: Set that mixture (inside of the Erlenmeyer flask) in the large bowl with water and ice and allow to cool.
3: In the separatory funnel, add about 120 ml ICE COLD water. Then
SLOWLY add 75.1g sulfuric acid.
4: Rig the separatory funnel so that its above the Erlenmeyer flask and may drip into it. Allow the sulfuric acid mixture to slowly drop into the GABA/Sodium Nitrite mixture (NO MORE THAN ONE DRIP/SECOND and no more than 20ml/hour).
NOTE: This process should be done outside or with very adequate ventilation as a VERY poisonous gas is produced by the reaction.
5. Let sit for 24 hours or until no more bubbling is seen.
6. Add another 150.1g of sulfuric acid to the mixture. (
Not sure one the addition time or if water should be mixed with the sulfuric acid first... some help here?) Let sit for 6 hrs.
7. Clean the separatory funnel.
8. In the separatory funnel, mix 150ml DCM and the GABA/sulfur/sodium mixture and shake well. Allow to sit until separation can be seen (2 layers of liquid). Remove the DCM portion and SAVE. It will be the bottom portion. With the remaining portion, again add 150ml of DCM and shake. Again, remove the DCM/GBL portion. Repeat 3 more times. (if any part of this step is wrong or could be explained more clearly, let me know and I will modify it.)
9. Combine the multiple DCM/GBL separations.
10. Boil off the DCM (at approx 100C?) till only the GBL remains (which should be yellow/brown liquid).
11. (optional, for added purity and enhanced taste) Simmer the GBL at 100C with approx. 3-5g of activated charcoal while stirring vigorously (magnetic stirbar recommended) for about 5 minutes. Then filter through a 5mm thick layer of celite.
12. Distill the GBL in your distilling apparatus at 198-202C. (If someone wants to make a full write up of the distilling process I will add it).
13. Mix 90.1g baking soda and 370ml distilled water.
14. Simmer GBL and baking soda mixture at 100C for 30 min to balance the PH by forming NaGHB. (I prefer to use NaOH for this step)
15. Redilute with water to desired potency.

Once again, pls let me know of any suggestions or mistakes/misleading statements as I have just woken up so I'm sure there will be
