実験手順
800 parts of mesityl oxide, 200 parts of 3-methyl-2-buten-1-ol (prenol) and 2 parts of formic acid are heated at 250°C for 3 hours in a vibrated autoclave holding 2500 parts by volume at a pressure of 60 atmospheres. The reaction mixture is worked up by distillation and gives 190 parts of 4,8-dimethyl-3,7-nonadien-2-one having a boiling point of 60° to 62°C at 0.2 mm. The yield is 78% of theory at a conversion of 63% based on prenol.
