实验步骤: Kirk-Othmer i.b.i.d. discloses that unsymmetrical dialkyl ketones are prepared by passing vapors of two different fatty acids over an alkaline earth oxide at elevated temperatures. It is stated that the product necessarily contains the three possible ketones and in the example given a mixture of acetic acid and butyric acid are reacted in the vapor phase at 300° C. on a manganese dioxide catalyst to produce 16% methyl ethyl ketone, 24% propyl butyl ketone and 60% ethyl propyl ketone. are prepared

实验步骤: 14 Grams of powdered (50 mesh) magnesium metal is suspended in 80 ml of ether and activated by addition of 200 mg of mercurie chloride. A solution of 38.4 g of 4-octanone and 36.6 g of propargyl bromide in 120 ml of ether and 50 ml of benzene is added dropwise at a rate which produced a gentle reflux. After the addition is complete, the reaction mixture is stirred for several hours and is then poured into 500 ml of cold 5% sulfuric acid. The organic layer is separated, washed with water twice, dried over sodium sulfate and stripped of solvent. The residue is distilled under vacuum to give the title product. produced a gentle reflux After the addition The organic layer is separated washed with water twice dried over sodium sulfate The residue is distilled under vacuum
