ingredients: Methanol, Gamma-valerolactone (GVL) Sodium Hydroxide (Lye)
Equipment: Beaker Vacuum filter Pyrex dish
Synthesis:
I started off by putting ( 40ml of methanol ) in a beaker and added ( 6 gr sodium hydroxide) to it, the heating was put to low and stirring was turned on till everything dissolved.
Once all sodium hydroxide dissolved in methanol I started adding (15ml of GVL ) very slowly drop wise stirring and heat is still on. After all GVL has been added I let the reaction run with heat and stirring for probably 20-30 more minutes.
By this point the mixture is slightly thicker and poured into a Pyrex dish placed on hot plate on very low heat until all methanol has
evaporated and you are left with crude GHV.
The crude GHV is crushed powdered and placed in a vacuum filter and washed cleaned with (cold acetone ), when dried you should be left with white crispy GHV powder
EDIT : GVL can be easily purchased online it is NOT a watched precursor
