Reaction Steps
In an autoclave, a mixture of 120 parts of 4-methyl-2,2-di-n-propoxy-4-pentene, 50 parts of prenol and 170 parts of cyclohexane is heated with 3.4 parts of formic acid for 4 hours at 160°C. Fractional distillation gives 57.5 parts of 4,8-dimethyl-3,7-nonadien-2-one, equivalent to a yield of 89% and a conversion of 67% based on prenol.
