I tried synthesize Ethyl derivated cyclopentadienyl tris(dimethylamido)Zirconium
But I have some problem in purification process
I want to remove all the solvent from product (toluene)
but it left always, even I dried it with vacuum all night.
And one more, when washing apparatus with acetone, it makes very fast reaction and makes fume.
I don't have idea why it react with acetone
