help base with sodium carbonate

[Dimitrius]

Salt is your best bet to break emulsions, loads of it

He may try that a little later.

Thanks for the tip.

Shitloads of salt, heating, mechanical stirring, or filtering through cellite/diatomous earth are ways to break emulsions. Did you shake or swirl before this formed?

No, no shaking or swirling hard.

Just a gentle stir by the magnetic stirrer...while adding the base and while adding the limonene.

when swim got this same mix of oily foam(which is mostly water) he siphoned the foam, and as much of limonene into a small glass jar with lots of surface area. he then submerged the jar in a hot water bath, and it got REALLY HOT then it broke flat leaving a lot of brown water at the bottom.

heaps of salt might do it too. is salt soluble in d-limonene?

if swiy has a way to suck all the foam out--no worries if water comes with it--put into another jar and really heat it up, emulsion should break.

He's not sure what he will do with the rest of the solution. He will probably either evaporate it down and proceed with lime. He may try lye.

He's tired and sick, and will have to work on this at a later time.

couldn't it be evaporated down and based with carbonate as well?---sorry, swim really wants to see success with sodium carbonate!
hope u feel better, too

Yeahhh.....he poured the test out. He didn't want to bother with it anymore. It's not a huge loss or anything....1/5th of 150g...30g.

He's going to evaporate the remaining 400ml down and base with CaOH2.

I suppose?

But if it's evaporated down, or the 'just wet enough' 'semi-dry' method is used, then one might as well use calcium hydroxide....it's a stronger base.

For SWIM it's actually easier to acquire calcium hydroxide than it is sodium carbonate. He either has to make his own sodium carb or buy it online. Calcium hydroxide he can buy at Wal-Mart or a grocery store.

Is it hard to find where SWIY is?

i figure it would be easy to find lime, havnt looked locally tho.
ur right, going for a limetek is a safer bet.
\too bad about that emulsion. swim wonders if a different acid (other than acetic or phosphoric) may be better suited for this situation.
cheers

When you go out (not sure what part of the world you live in), look for Mrs. Wages Pickling Lime...

100% calcium hydroxide....454g for around $5 where I'm at.
