Versuchsvorschrift

5.0 Grams (28 mmol) of 1-methyl-2-(3,5-dimethylphenoxy)ethanol was dissolved in 10 ml of tetralin, and 0.5 g of a copper-chromium catalyst (203 SD, supplied by Nikki Chemical Co., Ltd.) was added. The resultant mixture was stirred under a nitrogen current (0.1 liter/minute) at 210° C. for 8 hours. The catalyst was removed by filtration, and the filtrate was distilled under reduced pressure to give 3.41 g of 1-(3,5-dimethylphenoxy)-2-propanone (boiling point: 88° C./0.35 mmHg, yield 69%).
