With the vigorous stirring I use in my reactor, and keeping it at 65c, I seen temp increases the faster I spin. That’s what gave me the idea of using a heater/chiller to keep the temp more stable.
As I increased the speed slowly, I would drop the temp on the jacket of the reactor till I was able to achieve the fastest RPM stir and keep it at 65c so I can see some of that being exothermic. Trying like hell to not over shoot by moving slow on raising RPMs and consistently dropping the chiller temp as to not create too much heat from the reaction.
If you increase the stirring, you slightly speed up reactions. By mechanically increasing convection, the reaction relies less on slower diffusion of the reactant(s) toward the catalyst. Thus it produces more heat.
Hard enough to do this shit, get ready for Christmas, and make sure virtual schooling is running smoothly for the kiddos and take time to run an hour 1 direction to run more shit down there.
After the 1rst of the year, I’m getting my own analytics FFS.
No… I was dialing in D8 to see how close I could get to low D9. I have a tendency to bounce around with shit like this so I wanted to lock in this process before moving to D9.
That’s next and already have (what I feel to be) the perimeters to flip those numbers.
Heptane and pTSA, not dried, and no argon for this run.
Dang… I got 90% in heptane once but not in 30 min- seems like it isn’t done until the solution goes to a deep red rust color, like oxidized blood. I find the tines can be all over the place if the temp changes in small increments like 5C
If we increase the amount of acid in a system like ptsa and toluene/heptane where things are inmiscible. Let’s say we know the minimum amount of acid needed to get a full conversion. What if we raise the amount of acid by factor 10 or 20. What exactly is changed due to the higher amount of acid?
Would this speed up the rxn and if it does, what is the reason for it?
Higher rate of successfull collisions, increase of energy, nothing will change or something else I am not aware of atm?
