(wareami: "Will it ever sink in?", Stimulants)) will also work.
These figres are slightly different but should still work O.K.
For every gram of pseudo/ephedrine, use -
1.2gms Iodine,
0.6gms red phosphorous, and
0.8ml of distilled water. Eg 5gms pseudo, 6gms iodine, 3gms red phos, and 4mls of water.
Add the pseudo, the RP, and the dh20. Then add the iodine in small potions at a time, waiting for the reaction to subside before the next addition.
An oil bath for the flask is a good idea.Turn the heat on, reflux for atleast 24hrs with the INTERNAL flask temp of around 100°c. Remember the oil temp will bee higher than the internal flask temp. To find the difference, have some water in your flask and wait untill it starts boiling (full boil). Measure the oil temp, it may be 110-125°c. So you want your oil at that specific temp for your rxn.
Dont forget to have a condenser attached to the top of the flask. A balloon on the end of the condenser will stop any HI gas and odours escaping.
When its finished, extract the meth with and acid/base extraction or a steam distillation. see -
