Swim was over at chemfinder and looked up safrole and isosafrole. Safrole has a density of 1.095 and the isosafrole at 1.12<img src="../forum/images/icons_lightgrey/shocked.gif" alt="shocked" title="Shocked" heigth="15" width="15">Now swim mixed a small amount of iso and safrole and expected the iso to go to the bottom and safrole on top. Nothing happened. Is this because it is essentially the same substance? Swim figured if anything did happen, it would take a little while considering how close the two are in density. Still nothing though. Any ideas?<img src="../forum/images/icons_lightgrey/tongue.gif" alt="tongue" title="Tongue" heigth="15" width="15"><br><hr>We'll soon FIND OUT if I'm a chemist or not!

The density argument does not hold when the two liquids are miscible with each other. If you mix water and coffee (which have slightly different density), they will not form separate layers, but instead a homogenous solution. The same thing goes for safrole/isosafrole. <br><br>Only when immiscible liquids (like toluene/water) are poured into the same container, one will float on top, and that is the one with the lowest density.

It would be hard to tell unless the safrole and isosafrole were different colours. Put a few drops of dye in the iso and then mix them, wait and see. But like Big R says, they are miscible and wont form a layer. But somehow cheese thinks that after time the two WOULD form two layers because they are oily. Cheese don't know sheeeit. What are you trying to get out of this experiment anyhow pickles? It's fun to fuck around though, cheese wishes cheese had enough safrole to play around with it.<img src="../forum/images/icons_lightgrey/smile.gif" alt="smile" title="Smile" heigth="15" width="15"><br><hr> Cheeseboy-a whiteboy with Soul Like a black guy without soul<br>May The Source Bee With You Always.

Lets say for instance you had a mix of iso and safrole..

Just as ethanol and water won't spontaneously separate from vodka, neither will mixed isosafrole and safrole. It's a question of thermodynamics...

Drivel. Drivel. What an excellent word! Thanks, Chromic, for the chuckle. You have expanded my vocabulary and cheered my afternoon. <br><br>Maybe we can make an icon to represent drivel. We could then spray it over most of the posts (including many of mine, I'm embarrassed to say). Drivel. I love that word: it sort of rolls off the tongue in a haughty, teutonic way. Very classy putdown. Well said, Chromic. Cheers, mate.<br>
