Embodiment 1
[0067] Add 20kg of raw materials 3,5,5-trimethyl-2-cyclohexen-1-one, 40.0mg cobalt acetylacetonate, 900.0mg phenol The mixed solution of oxazine, keep the top pressure of the reaction distillation tower at 2.4barA, then slowly raise the temperature of the tower kettle to boiling, the temperature of the kettle is 259°C, after the reflux is established at the top of the tower, slowly increase the reflux flow at the top of the tower to 80kg / h, after total reflux for about 1h, the top of the tower began to withdraw material at a rate of 5.0kg / h, and at the same time, the fresh raw material 3,5,5-trimethyl-2-cyclohexen-1-one was fed into the tower kettle, The feed rate was 5.0kg / h, and the volume of the reaction liquid in the tower was kept constant during the whole rectification process. After 720 hours of stable operation, the temperature of the still was maintained at 259-261°C (the temperature increased slightly as time went on). The extracted materials are analyzed by gas pha...
