Based on experience of doing plant extractions in the lab I suspect that you will just get a green gunge which if left to settle out will consist of a pulverised layer of spinach at the bottom with a clear to semi opaque green liquid on top consisting mainly of acetone in which will be dissolved the chlorophyll and carotene from the leaves.

Using acetone based nail varnish remover to do the extraction and a piece of paper you could try separating the pigments by chromatography as in these articles. Don't worry about all the fancy solvents mentioned since the nail varnish remover should suffice for both extracting and running the chromatogram. I did this once for a whole range of inks and it's truly amazing to see all the individual pigments in inks.

Sounds like you were very lucky because a chemistry teacher acquaintance who first mentioned this to me says that the result (partly because of the highly volatile nature of the acetone and mainly because of the chemical reaction with spinach) is KERBOOOOM!

Do you still have your eyebrows?

He is/was either a very poor chemistry teacher or has been pulling your leg P-K. There is absolutely no way that spinach and acetone form an explosive combination. As you will have seen in the links that I posted, there are no dire warnings about mixing the two materials.

I have a feeling that if the two are whisked in  a blender  it is a slightly different scenario. Acetone fumes caused by the violent agitation in a kitchen scenario with naked flames about ?

I totally agree about the risk of acetone vapour and naked flames  Ant, but if you look through P-K's comments again you will see quite clearly that the teacher considers the  chemical reaction with spinach to be the greatest potential risk.

Not to mention the risk of eye injury if you are using a plastic blender jug which the acetone would (eventually) melt!

Why on earth would anybody want to mix spinach with acetone in a blender anyway?

My chemistry teacher was an American who had a nifty line in experiments usually involving Bunsen burners and various volatile gases.

The quote I remember from him most was "Jeez, class! You gotta help me!" when his experiments invariably went disastrously wrong in clouds of smoke and wreaths of flames.

Great fun for us. Needless to say, we didn't learn much about Chemistry but we all became more than proficient at first aid.
