Seroto9n:
Snakket du om å koke det til fastform for å finne ut konsentrasjonen? Muligens jeg prøver det også.

GHB ikke vil få en konsentrasjon over omlag 1.2 g/ml på 1 atm når det er hygroskopisk stabilt. Jeg målte ut 20 ml av det produktet jeg fikk og veide det til 25,27 g, så la oss gjøre litt matte.

Først finner jeg massetettheten til produktet jeg har fått.
ρTotal=g/ml
ρTotal=25,27/20=1,2635 g/ml

Så tilbake til den øverste likningen.
1,2635=(1/(100-x))1+(1/x)1,2

Jeg løser for x og får to svar.
x=0,957393
x=99,2009

Siden vi skal ha en prosentfaktor så må 0<x<1, dermed blir ρNaGHB=0,957393 som da er det samme som 95,7393%.

If, there being no other option, one were to procure NaGHB in liquid form from a third party then a safe and sensible route to take would be the following:

1)Test the pH of the solution to ensure that it is, at least, relatively pH neutral. It should, in fact, be slightly alkali. Somewhere in the region of 7.5 (although this depends on the pH of the water it was diluted with) is good.

2) Pour the liquid into a saucepan (any type will do as the substance is not GBL) and boil all the H2O off. The aim is to get the temp to 150c.

3) As the liquid is stirred it helps to release the H2O and, after a few minutes at 150c, there should only be light bubbling. Taking it off the heat and stirring it should show these bubbles to be getting smaller and less frequent until, once all the H2O has evaporated, stirring fails to elicit any bubbling.

4) With the saucepan now containing only molten NaGHB, it can be poured into a baking tray to harden and cool.

5) Once hardened this can then be broken up (grinding is not necessary and simply makes it absorb more moisture from the air) and weighed.

6) Weigh the amount required (it doesn't all have to be diluted at once) and place it in a measuring jug. Multiply the gram weight of the solid by five - this is the amount in ml's it should be topped up to with hot water in order to have a ratio of 1g of NaGHB to 5ml of water.
