OK... SWIDP is almost about to dream again… this time with all professional lab glass and equipment.
Ratios: 7.5g MBRP, 10.2g I2 (close to LG), 10g P-Fed, and 10ml dH20.
Procedure: MBRP will be obtained the usual way (minus the H2SO4 wash) from 35 boxes of matches. I2 will be used directly from the bottle. P-fed obtained from 4 24-pill boxes from a name brand company that has Pseudoephedrine HCl 60 mg, Chlorpheniramine maleate 4 mg, lactose, magnesium stearate, potato starch, povidone, and 17267 different gakks
per pill.
The pills will be extracted with Fester's KOH/Iso procedure. The P-fed will then be recrystallized via STE. 1ml of dH20 will be added to a 100ml RB flask to wet it a little bit. The 10g of P-fed will be added… then 7.5g MBRP is added and mixed in real good. The flask is put into an oil bath and a 300mm Allihn condenser is put on the flask. Flow of ice cold water is started thru the condenser and then I2 is added thru a thistle tube that almost reaches the bottom of the flask. The I2 is mixed around in the flask with a long bamboo skewer gently. Then the remaining 9ml of dH20 is added thru the thistle tube and a flat piece of glass is put on top of the thistle tube immediately after water addition to prevent any HI from escaping. A drying tube with anhydrous CaCl2 is then added. The hotplate is turned on to 25°C... then 50°C... then 75°C and finally 110°C within an hour. It is allowed to reflux for 24 hours @ 110°C (for an inside flask temp of 100°C) and then worked up by Geezmiester’s procedure on Rhodium’s website. The non-polar will be gassed via VE’s CaCl2/HCl procedure. The x-tals will then be vacuum filtered and washed with ice cold acetone.
1. Have any Bees extracted their feed by Fester’s procedure and then recrystallized by using STE? I would like hear how it went and what the yields where. Especially on name brand pills.
2. Is a 100ml RB flask and a 300mm Allihn condenser too small/short for this procedure?
3. Is it really necessary to do a H2SO4 wash of MBRP? Isn’t an acetone, HCl, and water washing/boiling sufficient?
Do any Bees foresee any major problems with this procedure? SWIDP would really appreciate whatever help/advice/recommendations other Bees can offer SWIDP.
