| titleOfInvention | A kind of method for preparing p-cymene from dipentene |
| abstract | The present invention relates to a method for preparing p-cymene from dipentene. The method includes the following steps: S1, continuously feeding nitrogen into the fixed-bed reactor; a catalyst bed is arranged in the fixed-bed reactor, and the catalyst bed is a θ ring packing loaded with a powdered catalyst; S2, Dipentene is vaporized at 180-220 ℃ to form steam, and the steam is passed into and filled with the fixed-bed reactor and then evacuated; the temperature in the fixed-bed reactor is 180-240 ℃, and the vacuum degree is 0.04-0.095MPa; the steam is continuously fed into the fixed-bed reactor to generate p-cymene by catalytic dehydrogenation reaction. The method can realize simple, efficient and continuous preparation of high-purity p-cymene, and the content of p-cymene is more than 92%. |
