In what solvent/solvent mixture under what conditions is ferrocene soluble but acetylferrocene is not?

Context is it's for recrystallization of acetylferrocene with ferrocene contaminant. What's the best way to go about performing this?

Answer #1

Solution:-

Nonpolar petroleum ether i.e mixture of hydrocarbons up to chain number 8 will be the best solvent for the seperation of ferrocene from acetyl ferrocene because ferrocene is non polar and soluble in petroleum ether but acetyl ferrocene is non polar which will not be soluble in petroleum ether.

So petroleum ether will wash off ferrocene and leave behind the acetyl ferrocene.

    These questions are from an experiment where we had a mixture of Ferrocene, acetylferrocene and diacetyl ferrocene and we separated each by using column chromatography. Before doing the column chromatography we did TLC analysis to ensure that we did, in fact, have a mixture of these 3 compounds. During the column chromatography we first eluted the ferrocene using pure hexane. Then we eluted the acetylferrocene using a 1:1 mixture of hexane and methylene chloride. Then we eluted the diacetylferrocene using...

    You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

    please answer all parts I am trying to check my answers. Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...
