I thought that you was supposed to use .8 RP 1.0 E and 1.2-1.5 on I2.

Don't think, just do as I tell you! Ratios vary depending on many variables, such as....
Size of rxn,
quality of reagents,
Desired speed of rxn,
Whether heat wil be used,
etc etc etc.

Just use what I have listed, it works, I guarantee it! I would not have written it if it didn't! Do you think I made a typo with those figures? I wrote them for a reason. Despite what "you think", these figures have been pretty standard for HI/RP for many moons. Read around and you'll see. When you have a reasonable understanding of the rxn, one can adjust ratios depending on the specific variables in play. By all means use whatever ratios you like, but be prepared to waste reagents unnecessarily, and or fuck the rxn due to it going too fast or too slow. In fact literature shows that with a reflux ratios can go very extreme and have as little as 5-10% RP. But again, this is not suitable for this rxn, as with this write-up we are trying to acheive a symbiotic (don't know WTF?)balance between the speed of a P/P, with the yeilds of a classic 36 hour reflux. So ratios are worked out to acheive a nice fast rxn without losing control and going too fast which leads to broken molecules (smashed ephedrine) and lowered yield.
Do you understand, or have I just typed all this shit for nothing?
Where's FMAN?

Besides, you should know better then to question the placebo!

but what do you more experienced bees use to circleulate the ice water throught the condenser

---

-go to home depot and buy yoourself  a small fountain pump.

- Buy a small syrofoam cooler.

- Poke holes in the lid  through which to run your water lines and electrical cord.

- Cover the pump with ice.

- Add just enough water to  cover your pump.

- Also, keep your receiving flask in an ice bath.


This setup works great for reflux too. Only one ice change required in a 16 hour reflux.
If your tubing does not fit tighly in the pump, wrap it with teflon tape.

cost- US
  small fountain pump   < $15.
  small syrofoam cooler < $2.00

Keep the PH up.... Don't know why but distillation DOES slow way down below PH 10

What if you were to just add NaOH in you'r pressure cooker?
Would this keep you'r PH up?

---

The pressure cooker just supplies steam. If you add NaOH to it it will just stay in the pressure cooker. Instead, just add a shitload of NaOH to the flask containing the product.
You really don't even need an external source of steam just add water (and NaOH) to the product flask and heat this.
