Web3 jan. 2008 · pinacolone Using a school procedure (Pavia et al) I recently made pinacol hexahydrate. I confirmed its identity via melting point. Then I converted this to pinacolone (aka 3,3-dimethyl 2-butanone) using H2SO4 followed by a simple distillation. Noting that this is a methyl ketone I assumed I could use the iodoform test for confirmation of identity. Web7 apr. 2024 · The melting point is the temperature where the solid and liquid phases are in equilibrium with each other, and the change in free energy ( Δ G o) for the process (solid ⇌ liquid) is zero.
