The invention relates to the technical field of production of an aromatic compound 9-fluorenone, in particular to a preparation method of the 9-fluorenone. The preparation method includes the steps as follows: 1) taking industrial fluorene, benzene series solvent, sodium hydroxide and quaternary ammonium salt, and adding the four components in a four-mouth bottle; 2) stirring the mixture in Author: 王广兴, 王守凯, 方田, 焦宾, 姜辉, 臧娜. Reaction engineering simulations of a fluidized-bed reactor for selective oxidation of fluorene to 9-fluorenone. Chemical Engineering & Technology , 17 (3), Cited by: Oxidation of sp 3 C–H bonds has attracted increasing attention, and the aim of our work is to prepare catalysts for oxidation of sp 3 C–H bonds using O 2 without an initiator. In this paper, a series of Co–Cu bimetal oxides with different Co/Cu ratios were synthesized by a sol–gel method and tested for catalytic oxidation of fluorene to fluorenone using molecular oxygen as an oxidant.

WOA1 en. The sulfur concentration in the raw material fluorene can be adjusted at or below 0. The atomic ratio of each added element was as follows. SUMMARY OF THE INVENTION. For reproduction of material from PCCP: Reproduced from Ref. FIGURE is a schematic diagram of a reaction apparatus to be used in examples and comparative examples herein.Reaction engineering simulations of a fluidized-bed reactor for selective oxidation of fluorene to 9-fluorenone. Chemical Engineering & Technology , 17 (3), Cited by: 01/01/ · Maximum 9-fluorenone selectivity in air oxidation of fluorene as function of catalyst composition (Vo: Fe: Cs atomic ratio) and its calcination temperature at various reaction temperature (CF = Vol. %) 3 2 Adsorption of reactants. For characterizing the adsorption properties of the solids the catalytic surface pseudo-adsorption constants and heats of adsorptions were derived from kinetic Cited by: 1. Oxidation of fluorene to 9-fluorenone was also obtained in vitro in a system that contained manganese, unsaturated fatty acid, and either crudeP. chrysosporiumperoxidases or purified recombinant manganese peroxidase. The oxidation of fluorene in vitro was inhihited by the free-radical scavenger butylated hydroxytohiene but not by the lignin peroxidase inhibitor NaV0 3. Manga-nese(III)-malonic.

Copper-doped Co3O4 with a high specific surface area has been prepared by using mesoporous silica KIT-6 as a hard template, which showed exceptional catalytic performance (99% conversion of fluorene and 99% selectivity of fluorenone) for catalytic oxidation of fluorene to fluorenone using molecular oxygen as the oxidant in the absence of a radical initiator or other cocatalysts Cited by: 1. Download PDF US Patent References: Process for making fluorenones: Walters et al. / Method of oxidizing compounds having activated methylene radicals: Ma: / Process for the production of fluorenone by catalytic oxidation of fluorene: Finger: / PREPARATION OF FLUORENONE: Cited by: 6. OXIDATION OF FLUORENE/ COLUMN CHROMATOGRAPHY In this exercise we will subject the organic hydrocarbon Fluorene to air oxidation and then purify the product by Column Chromatography. Fluorene is suprisingly acidic (pKa ≈ 20) due to the stability of its conjugate base. Therefore in basic media, it will be in equilibrium with a modest amount of its conjugate base. 14/12/ · This oxidation procedure is more efficient than the chromic acid-amberlite procedure, which is a heterogeneous solid-liquid reaction that proceeds poorly due to the requirement of very efficient agitation. IMPORTANT SAFETY INFORMATION 9-Fluorenol is listed in the EPA inventory under TSCA. Wear gloves and avoid all contact with skin eyes, and clothing. 9-Fluorenone is listed in the .
