[0012] Referring to Figure 1The utility model discloses an isobornyl acetate fractionation device, including feed pipe 1, clear separation tank 3, first discharge pipe 5, high level tank 8, second discharge pipe 10 and fractionation column 9, the bottom of clear separation tank 3 is connected to feed pipe 1, be provided with first filter screen 4, second filter screen 2 and sodium carbonate solid particle in clear separation tank 3, first filter screen 4 with second filter screen 2 are arranged in the inside upper and lower interval of clear separation tank 3 to form with the acid cavity between first filter screen 4 with second filter screen 2, sodium carbonate solid particle is filled in the acid cavity, one end of first discharge pipe 5 is connected to the top of clear separation tank 3, the other end of first discharge pipe 5 is connected to high level tank 8, be provided with feed pump 7 on first discharge pipe 5, one end of second discharge pipe 10 is connected to high level tank 8, the other end of second discharge pipe 10 is connected to fractionation column 9.

[0013] The isobornyl acetate fractionation device sets up feed pipe 1 for guiding the kettle product of initial fractionation into clear separation tank 3. The first filter screen 4, the second filter screen 2 and the sodium carbonate solid particle filled in the acid cavity arranged in the clear separation tank 3 form an effective acid-removing structure. The sodium carbonate solid particle can react with the free acid in the product, thereby adsorbing and removing the free acid, and also absorbing trace water. The arrangement of the first filter screen 4 and the second filter screen 2 can fix the sodium carbonate solid particle, prevent it from flowing with the material, and preliminarily filter and clarify the material. The first discharge pipe 5 connects the top of the clear separation tank 3 and the high level tank 8, and is provided with a feed pump 7, which can pump the material subjected to acid removal and preliminary clarification to the high level tank 8 smoothly, so as to perform subsequent final fractionation.
