yes it's possible to make but like I said the purest of purest acetone is 99.8% that's the purest one can get, HPLC grade acetone is what we used for analysis-it cost about $400 for a bottle and you can't get purer than that. . .believe me it's what I do for a living. . .anyways, a mass spec is better for looking at what chemicals are present, and to see signals of certain groups and individual cleavage patterns. IR is to determine the type of bonds and to see functional groups so both are important when Identifying a chemical.
Anyways, there is always error in chemical synthesizing since the precursors determine the purity and out come of the product, but for our purposes, nail polish remover is suffice.
I did As level (a qualification in secondary school in UK) on chemistry
Hydrocarbons and halogenoalkanes/enes was my favourite bit, sadly physics was calling me and decided to drop chemistry(i am now doing physics,maths and biology) I do regret it but I needed to focus on physics, also biology was a lot easier to do.
