Synthesis of pinacolone

Preparation of pinacolone (3,3-dimethyl-2-butanone)

Preparation of pinacolone (3,3-dimethyl-2-butanone)

Preparation of pinacolone (3,3-dimethyl-2-butanone)

20 grams of pinacol hydrate are dissolved in the warm solution of a mixture of 80 of water and 20 ml of concentrated sulfuric acid and the mixture is boiled for 15 minutes under reflux. When the reaction is complete the solution is cooled and transferred in the flask for the distillation. The distillation is performed until no more pinacolone comes over. The upper layer containing crude pinacolone is separated by the means of the separatory funnel, dried over calcium chloride, filtered. In order to obtain pure product, the crude pinacolone is redistilled by collecting fraction passing at 103° C to 106° C.
