It’s a pain. Would love to use a transmission style agitator (like a washing machine). I think that’s a lot of the problems. Not enough surface contact. Think that’s why the smaller runs (in separatory funnels) seem to do better because of all the shaking you can do.

Any of you innovators got any ideas on this?
God I hope when someone goes to the hospital from smoking solvent dye that they cite this post in the court documents. A self-proclaimed consultant that says if you’re stupid enough to listen to him that you deserve to die by “natural selection.” You can’t make this up.
I’ve done ptsa/pentane before; RT for 48 hours; saw a total conversion; this was with 80-85% cbda input; I yielded some interesting results. This was done in a 500ml reactor; jacketed, and at -10c with an argon blanket and a glass sparging arm.
It yielded some pretty anomalous results; a weird cloudy oil; in retrospect; the cloudiness was probably dude to lipid contamination; my starting material was pretty poor; it was etoh extracted CBDA precipitated with a water antisolvent addition. I didnt push too hard on it; the long reaction time made me shy away. Didnt have a d8 thca standard for analysis.
As to better solution to agitation; a rotovap would probably work pretty dam well for what your trying to do; maybe with a chilled bath some how.
The best would be a reactor with an overhead stirrer with a programmable VFD that allowed you to reverse it; program simple sequence that drives it forward for X ammount of seconds; then reverse for X ammount of seconds; make the stirring a little more “chaotic” and promote more kinetic interactions.
The rotovap would be a good one! Set it where the bulk solution hits the top of the flask on rotation then cascades down!
BRILLIANT!
The programmable VFD is also a good one!
yea and charge with nitrogen via the injection tube/valve; shit you could even sparge with it if you extended the tube out a bit! throw a bubbler on the vacuum port and your golden
im going to try this for the funzies
Funny how when ya talk an idea out in a hypothetical situation, it turns out to invent a new purpose for a piece of equipment. 
necessity is the mother of invention! just pre-emptively fill the receiving flask to help better facilitate reflux, dont wana recover the solvent; just have it reflux
With pentane that’s exactly how I did it on the first run. The evaporative cooling of the reflux kept the flask and soln. cold. I just got my Glenn mills sonotube into the lab last week and I’ll be testing soon. It’s a ultrasonic flow tube with no probe the transducers are on the outside so no ti contamination. I’ve been reading several papers on the enhanced affect of untrasonics on heterogenous catalysis and I think this is a sound strategy for the mixing issue.
Need a simple plug on the receiving flask so you don’t need to fill it.
Love how he used the word chemist and “bruh” all in the same argument.
Guess you can take the “chemist” out of the ghetto but, can’t take the ghetto out of the “chemist”…
shit just a new condenser without a joint for the receiving flask!! maybe incouperate some form of dean stark tho
ultrasonics would probably be clutch too!
give me an excuse to buy an ultrasonic reactor xL
This is headed in the right direction! You can get rotos without glassware ultra cheap!
you dont need no stinking reactor 
Ya gotta rename it to fit! A new form of horizontal reactor.
Patent it.
Tell people it’s your IP.
Threaten to sue everyone.
Make loads of 
I agree! Well thought out!
and the R O T O R E A C T O R was born
I’m serious, man! This could be a HUGE breakthrough for reactions!
Cascading reactor!
I’m on the hunt for pieces!
Even a baffle in the inside of the reactor would work too.
1 inch holes
About 4 inches in width, 1 inch thick that attaches to the side of the reactor to dissipate the circulation. PTFE and removable for cleaning.
lessss go!
i got a little 2L roto doing nothing; lemme talk to my glassblower friend and see if he can chop the receiving port off; feel like it needs a thermowell by the vapor duct so you can log vaportemps
rig it up to schlenk setup
