Description
Technical field
The utility model relates to a kind of chemical industry equipment, especially relates to a kind of Special reverse for 9-Fluorenone production and answers flow container.
Background technology
9-Fluorenone another name Fluorenone, molecular formula C13H8O, in yellow oblique square crystal body, fusing point 84 DEG C, boiling point 341.5 DEG C, is a kind of important fine chemical material, is widely used in the synthesis and preparation of fuel, photoconductive material, medicine and luminescent material.
both at home and abroad relevant report fluorenes be oxidized the method for preparing 9-Fluorenone and major technique as follows: Nippon Shokubai Co., Ltd's Chinese vanadium metal, titanium and alkali-metal catalyst in 1996, vapor phase method is adopted to prepare 9-Fluorenone, reaction temperature more than 400 DEG C, productive rate is lower than 95% (ZL.96123084.3).Vapor phase method oxidation fluorenes prepares 9-Fluorenone, complicated operation, and temperature requirement is higher, and cost is high.
people's [Shanxi chemical industry such as the abundant halls of department of chemistry of University Of Shanxi bear in 1989,2,17,1989] and people [fuel and the chemical industry such as Anshan Iron & Steel College height Wei Min in 1999,30 (2), 66,1999] report using methyl-sulfoxide (DMSO) as solvent, potassium hydroxide as catalyst, reaction temperature 56 DEG C, air oxidation fluorenes is for 9-Fluorenone, productive rate is not less than 93%, the method dimethyl alum used boiling point is high, adds a large amount of water and remove precipitated product after reaction, processes 10 times of waste water containing DMSO to solvent and can bring larger difficulty.Within 2006, fluorenes is solvent with methyl-sulfoxide by Shanghai Jiaohua Co., Ltd, and NaOH is catalyst, and reaction temperature 50-100 DEG C is reacted prepare 9-Fluorenone, productive rate 96% [patent publication No. CN1754867A] with industrial oxygen.This method selects solvent DMSO boiling point high (DMSO has decomposition higher than when 90 DEG C), difficult solvent recovery.The technique of Osaka, Japan gas Co., Ltd. is: fluorenes is in alkalescence or neutral flux, and add alkali and quaternary ammonium compound, with air oxidation, final Fluorenone yield is only 86.9%.Unexamined Patent 7-82207 reports that the Fluorenone preparation technology of Myake is: fluorenes be dissolved in toluene the aqueous slkali of 48% and 50% (PhN+Me3) S04 solution catalytic action under, blowing air, through oxidation reaction 3 hours, the refining Fluorenone obtaining purity 100%, yield was 92.2%.Unexamined Patent 7-82206 reports, the process for preparing fluorenone of the people such as Ito be by fluorenes and quaternary ammonium salt molten with aqueous phase in alkaline solution, and adopt boiling point to be the organic solvent of 80-150 DEG C, oxidation, then obtain through refining, yield is 95%.Produce a large amount of spent lyes, difficult treatment in above-mentioned two inventions, be unfavorable for environmental protection, and owing to using alkaline aqueous solution to be catalyst, greatly limit the ingredient proportion of raw material fluorenes, cause volume productivity lower.Application number is that the Chinese patent of 200910187363.X (September 15 2009 applying date) discloses " a kind of method of producing 9-Fluorenone ", take toluene as solvent, quaternary ammonium salt is catalyst preparing 9-Fluorenone, when the method reaction temperature is 60 ~ 80 DEG C, product can reach 99% through the purity that is once recrystallized, when reaction temperature is at 50 ~ 60 DEG C, need just can obtain sterling through twice recrystallization, cost is higher.
