Shaking vs. stirring | Bookmark | ||||||
when doing the KRV/SRV thing, using methanol as solvent and 1g pdcl2 per 50 mL safrole, why can't stirring be used instead of shaking? KrZ's method with DMF/O2 uses stirring and gets great yields. Why is it that shaking is emphasized in the KRV/SRV reaction? Swim's stirrer is pretty damn fast on 10, why would oxygen not be absorbed by stirring, but by shaking only? if stirring worked, it would be a much easier reaction, right? no more shaking, you could just set the thing on the stirrer and come back every half hour to repressurize. |

Shaking stirring, Shaken'dog? | Bookmark | ||||||
Shaking, and swilling(swirling) Well, really you want to mix the contents right? -Place 6-8 marbles into SRV -watch yield go up,. hellski IQ is the rate of logic, as Wisdom increases logic, fear & compromise decrease to reveal objectivity |

Try modifying the stirbar to get greater induction of the gasses. A friend I know was working on an invention like this. Basically involves drilling holes in a stirbar to cause induction of gasses into solution as it spins, try it sometime I don't give bad advise, unlike some people around here. |
