Acetone from Urea ?
i don't know if it's possible really,but can anyone think of anyway ?

Ooh, reminds me of my six degrees of separation chemistry game in whimsy.
Let's see...
(1) Urea + water + heat over a platinum catalyst to get an equilibrium mixture of N2, H2O, H2, CO and CO2, use adsorption to scrub out CO2 and water
(condenses).
(2) Apply very high-temperature Fischer-Tropsch (iron catalyst) to the Syngas to make hydrocarbons with lots of benzene and shorter olefins, distill
benzene from hydrocarbons.
(3) Isolate propylene from remaining hydrocarbons. Use all other remaining hydrocarbons as fuel for the process.
(4) React propylene + benzene to make cumene over an acid catalyst (e.g. zeolite)
(5) React cumene with oxygen to make cumene hydroperoxide.
(6) Hydrolyse cumene hydroperoxide with an acid catalyst to make phenol and acetone.
QED in 6 steps 
NOTE: Step (5) + Step (6) are industrially known as the Hock Process.

Come on now, delta, it can be done in half as many steps!
(1) Urea + ethanol to get ethyl carbamate.
(2) Dimethylate the ethyl carbamate using an Eschweiler–Clarke reaction to get ethyl N,N-dimethylcarbamate.
(3) Do a Grignard on ethyl N,N-dimethylcarbamate using exactly two equivalents of methylmagnesium chloride to get acetone. (very carefully and with
constant stirring, slowly adding the Grignard reagent to the ethyl N,N-dimethylcarbamate and not the other way around)
Presto! Acetone from urea in only three easy steps!
*EDIT* - Come to think of it, why not just cut out the first step all together and just dimethylate both nitrogens on urea at the same time to get
tetramethylurea. Then just do the Grignard in step three on that. Think it would work with tetramethylurea being so sterically hindered? Because if it
would, then that would be acetone from urea in not six, not three, but two easy steps!
/sarcasm
@OP:
Seriously, though, assuming acetone is OTC where you live, why not just buy it from the hardware store? The stuff is dirt cheap.

If you really can't get acetone, you could dry-distill calcium acetate with NaOH.

That produces methane. You just want to dry distill the acetate.
