----------------
Methamphetamine is prepared by the catalytic hydrogenation of ephedrine
in acetic acid, containing a small amount of perchloric acid as an
activator. This process requires from 4 to 5 hours, although some
say 6 to 8 hours, for completion. Methamphetamine may also be
prepared by the reaction between phenylacetone and methylamine,
then the final reduction to methamphetamine. This process requires
6 to 8 hours from completion.

Materials: 95-100% ethanol, Sodium Borohydride, 250 ml round bottom glass
flask, reflux condenser, rubber tubing, Sudafed nasal decongestant capsules,
glass extraction funnel, 1 molar Sodium Hydroxide, anhydrous Sodium Sulfate,
diethyl ether, Safety goggles, Safety shield ( plexiglass...1-2" thick ),
Safety apron and gloves. It's also advisable to have a dry chemical fire
extinguisher available at all times. Blue and red litmus paper, and
about a litre of saturated salt solution (1 gram per 23 mls).
At ALL stages, glassware should be kept very dry.

Theory: You will perform a catalytic dehydrogenolysis on pseudoephedrine,
converting it into methylamphetamine (speed, ice, or glass are common names).

Structure of synthesis: This procedure is broken up into two parts;
1) the production and purification of pseudoephedrine free base.
2) the production and purification of methylamphetamine free base.
