| titleOfInvention | Preparation method of 3,6, 6-trimethyl-2, 4-cycloheptadienone |
| abstract | The invention discloses a preparation method of 3,6, 6-trimethyl-2, 4-cycloheptadienone. 3-carene on CrO 3 βAl 2 O 3 Under catalysis with O 2 Reacting at 35 β for 24h to generate a product I taking 5-carene as a main component, wherein the conversion rate of the 3-carene is about 81.3 percent, and the selectivity of the 5-carene is 60.1 percent; the product I reacts for 4 hours at the temperature of 120 β under the pressure of 0-1 kPa, and is converted into a product II taking 3,6, 6-trimethyl-2, 4-cycloheptadienone as a main component, the conversion rate of 5-carene is 100%, and the selectivity of 3,6, 6-trimethyl-2, 4-cycloheptadienone is 98.7%; and (3) carrying out vacuum rectification on the product II to obtain the 3,6, 6-trimethyl-2, 4-cycloheptadienone, wherein the yield is more than 75%, and the purity is more than 95%. |
