Is it necessary to remove filter paper before sublimation of ferrocene (sublimation on petri dish on a hot plate with a beaker with ice placed on the top of the petri dish). Temperature should be less than 100 degrees Celsius.

It would probably be ok not to, but it is generally considered bad technique to leave your sample on the filter paper when you do a sublimation.

I got some orange particles floating in the beaker, but after vacuum filtration, the precipitate was completely brown (I guess impurities are present) What do you think?  The filtrate was dark blue, that means it contains ferrocenium ion, doesnt't it? How can I recover ferrocene from filtrate? Should I use SnCl2(as a reducing agent) or do you have other suggestions?

But you think it would be successful, right? It wouldn't be problem, I mean paper doesn't burn at 100 degrees Celisus, right?

[Mitch]

It should be ok. Again, it is bad technique to do it, so why do it?

I used relatively bigger Hirsch funnel than I should've used, so ferrocene is in really thin layer on filter paper. It still has to dry out, but I am not sure that I could remove the precipitate from the filter paper (I was doing microsynthesis)

dolphinsea14:, I've merged your two posts, and I'm sorry to you and Mitch: the mess the merge makes of your posts.

Please people, try to keep threads together.  If you have something to add, add it to your thread.  Don't make multiple threads.  What will you do -- reference the previous thread later?  That's confusing, and unfair to the person who missed your other thread.

Just put the filter paper in some good solvent and rinse the ferrocene off it, then evaporate the liquid down in whatever container you want to sublimate in.
