The chemicals you'll need: gamma butyrol lactone sodium hydroxide NaOH: also known as caustic soda. Sodium Hydroxide comes as either flakes or pellets, make sure to check purity with the supplier and buy the purest. The only other things needed to make the GHB is your kitchen stove, a pot to heat the solution in, and some pH paper.
Here's the recipe: You'll need a glass pot big enough to hold 2 quarts of liquid. Note that purchasing the lactone will certainly be suspicious and most probably get your name on a mysterious DEA list somewhere. Also note that the makers of the lactone never expected someone to drink the stuff so no thought has gone into the toxicity of the impurities which it will contain.
What commercial process is used to make the lactone?
Remember the lactone can be used as a wood cleaner. Into the glass container pour 1 quart of gamma-butyrol-lactone. Heat this liquid over a low heat. Lactone boils at about 192 degrees Fahrenheit, but you must not allow this to happen! It would be wise to check the temperature of the liquid with a thermometer. You want just enough heat to dissolve the sodium hydroxide into the liquid. Into the 1 quart of lactone start by adding one pound of caustic soda pellets. Heat the mixture slowly until the pellets dissolve. The ratio of the lactone to NaOH should be 1g NaOH : 2.02 ml butyrolactone. At 760 mm Hg the lactone boils at 204 C (convert it to Fahrenheit yourself, [9/5*C]+32) The temp. will rise quickly on adding the NaOH. Slowly adding it would be the key. Then again, I also suspect that there might be problems dissolving the NaOH so perhaps this rise in temp. is not a problem. Once the NaOH is dissolved, check the pH of the solution with the pH test paper. It should be in the range of 2-4. We are shooting for a pH of between 6-7. You must add small amounts of caustic soda to the initial one pound amount, check the pH, add pellets, back and forth until the correct range pH, between 6-7 is attained. Once you have attained the, correct pH reading turn off the heat and let the solution cool. What you have now is a 50% solution of GHB (50% GHB, 50% water). For ideal measuring purposes, we want a 20% solution. To do this, you have to measure the total amount of liquid you have and add to it one and a half times as much water. At this 20% solution, one level teaspoon of liquid is equal to one gram of GHB if it were dry.
