1-Methyl-4-piperidone Usage And Synthesis
Chemical Properties clear yellow to orange liquid
Purification Methods It is best purified by fractional distillation The hydrochloride of the hydrate (4-diol) has m 94.7-95.5o, but the anhydrous hydrochloride which crystallises from CHCl3/Et2O has m 165-168o (164-167o) and can also be obtained by sublimation at 120o/2mm. The oxime has m 130-132o (from Me2CO). The methiodide crystallises from MeOH, the crystals with 1MeOH have m 189-190o, and the solvent-free iodide has m 202-204o(dec). [Lyle et al.
