Let's start by saying: You should not be making GHB if you can't multiply.
1mol NaOH + 1mol GBL --> 1mol sodium CHB
Molecular weight of sodium hydroxide = 40
Molecular weight of butyrolactone = 86
density of butyrolactone = 1.16 g/mL (0.862 ml per gram)
40 gm of na hydroxide for 86 grams of butyrolactone =
465 grams of sodium hydroxide for 1000 grams of butyrolactone =
465 grams of sodium hydroxide for 862 mL of butyrolactone =
539 grams of sodium hydroxide for 1000 mL of butyrolactone.
This means you are going to need 2048 grams, more or less, of sodium hydroxide.
Sodium hydroxide and GBL are both seriously corrosive. Wear safety glasses/goggles, and gloves. They can blind you. They can cause disfiguring burns. 2000 grams of lye, especially if present as several gallons of lye water, is enough to kill or disfigure you very seriously.
You absolutely must have a gallon bottle of white vinegar on hand to neutralise spills. Using water will only make a very large, very corrosive mess that will need a Hazmat team to deal with. Neutralising spills with vinegar creates relatively harmless sodium acetate - salt and vinegar potato chip flavoring.
Sodium hydroxide releases heat when dissolved in water, or when it reacts with GBL. Be careful adding sodium hydroxide to sodutions.
It can cause water to boil and even do things like light wet paper on fire. This means no flammable shit around.
Sodium hydroxide solutions will eat aluminum, steel, some plastics, rubber, copper, bronze, and glass. Again- it will also eat human tissue very effectively. In fact, assume it will eat everything. Especially if hot or concentrated. As it dissolves metals it will release hydrogen gas - so no aluminum crock pots for GHB cooking. High density polyethylene and good quality borosilicate glass (Pyrex) are OK, but the Pyrex will get etched over time.
Good idea to read some MSDS/hazrad sheets too... I will leave it up to you to figure out GBL...
