That is, 4-chlorochlorobenzene, 4-bromonitrobenzene, 3-chloronitrobenzene, 2-chloronitrobenzene, 2-chloro-3-nitrotoluene, 2-chloro-4-nitrotoluene, 2-chloro-6-dinitrobenzene, 4-chloro-2-2-nitrotolenene, 4-chloro-3-nitrotoluene, etc.
- the amount of the aromatic halonitrite compound used per mole of the fluorenylidene bisphenol compound is preferably at least 2 moles, preferably 2.2 to 2.5 moles.
- alkali metal carbonates such as sodium carbonate and / or carbonated lithium
- alkali metal hydroxides such as sodium hydroxide and / or hydroxide, and mixtures thereof
- a reaction solvent is not essential, but preferred specific examples include non-protonic properties such as dimethylformamide, dimethylacetamide, dimethyl sulfoxide, sulfolane, N-methylpyrrolidone and 1,3-dimethyl-2-imidazolidinone.
- a polar solvent can be mentioned.
- These reaction solvents are preferably used in a range of 1 to 50 times by mass with respect to the mass of the fluoroureidene bisphenol compound.
- copper compounds such as copper powder, copper oxide ( ⁇ ), copper iodide (II), copper acetate (II), or a mixture thereof can be used.
- These catalysts are from 0.1 to 1 0 0 wt% for a full O Leni bisphenols 1 0 0 mass 0/0, preferably in a range of 0.5 to 1 0% by weight.
- a highly reactive aromatic halonitro compound when used, the reaction proceeds smoothly but side reactions are likely to occur. As a result, recrystallization and purification of the target aromatic diamine will be extremely difficult. Therefore, when using a highly reactive aromatic halonitro compound, it is preferable to carry out the reaction in the first step without using copper or a copper compound as a catalyst. By doing so, a highly selective diaryl etherification reaction that does not require a purification operation can be performed. That is, by reacting fluorenylidene diphenols with an aromatic chloronitro compound in the presence of an alkali compound, a dinitro compound having a diallelite structure can be obtained.
- the first step first, a fluorenylidene bisphenol compound, an aromatic halonitro compound, carbonic acid in a vessel equipped with a stirrer, a thermometer, a Dean—Sta 1 k moisture device, and a return cooling pipe. Potassium, toluene, and dimethylformamide are added, and the temperature is raised to 110 ° C while maintaining the system in a nitrogen atmosphere, and the resulting water is distilled off azeotropically with toluene. When the distillation of water is completed, raise the temperature to 150 ° C and react for 3 hours at the same temperature. After completion of the reaction, the resulting reaction mixture is cooled to room temperature, poured into water, and the precipitated crystals are filtered off.
- the crude crystals are washed with water to remove inorganic salts.
- the washed crystal is washed with methanol and dried to obtain an aromatic dinitro compound.
- the aromatic dinitrate compound obtained in the first step is subjected to a reduction reaction. Since dinitro compounds are hardly soluble in solvents such as alcohol, which are commonly used solvents, the reaction hardly proceeds under typical reducing conditions. Therefore, it is preferable to use an aprotic polar solvent in consideration of some advantages in solubility and inertness to the reaction.
- aprotic polar solvent dimethylformamide, dimethylacetamide, dimethylsulfoxide, sulfolane, N-methylpyrrolidone and 1,3-dimethyl-2-imidazolidinone are used as in the first step.
- the amount of solvent used is based on the mass of the aromatic dinitro compound.
- the aromatic dinitro compound may not completely dissolve during the reaction. The reason is that the aromatic diamine produced by the progress of the reaction has sufficient solubility in the aprotic polar solvent, so that when the reaction is completed, the produced aromatic diamine is completely dissolved in the aprotic polar solvent. This is because the reaction mixture after completion of the reaction becomes a uniform solution except for the catalyst.
- the second step is achieved by a known nitro group reduction reaction.
- a catalytic reduction method using molecular hydrogen in the presence of a catalyst.
- Examples of the catalyst used in the reaction include metal catalysts such as nickel, Raney nickel, and platinum, and catalysts in which these are supported on activated carbon, alumina, or the like. These supported catalysts are 100 masses of dinitro compounds. / 0 for 0.1 to 100 mass%, preferably in a range of 0.5 to 30 mass%.
- the reaction temperature is 20 to 300, preferably 100 to 200, and the hydrogen pressure is atmospheric pressure to 5 MPa, preferably 0.3 to IMP a.
- the catalytic reduction reaction is carried out after adding the dinitro compound, catalyst and solvent, and at the specified temperature and the specified pressure until the hydrogen pressure does not drop.
- the solid catalyst is filtered off from the obtained reaction mixture, the filtrate is poured into water, and the precipitated solid is collected by filtration.
- the crude product can be washed with water and purified by recrystallization or the like as necessary to obtain the aromatic diamine according to the present invention.
- the temperature was raised to 150 and reacted at the same temperature for 3 hours.
- the obtained reaction mixture was cooled to room temperature, poured into 1500 g of water, and the precipitated crystals were separated by filtration. Further, the crude crystals were washed with 1000 g of water and filtered to remove organic salts. Similarly, it was washed again with water and filtered. Next, washing and filtration of the washed crystal (wet) with 1000 g of methanol were repeated twice, and then this crystal was filtered and dried to obtain 254 g of the corresponding aromatic dinitro compound. The yield of the obtained dinitro compound was 96.2% based on 9,9-bis (4-hydroxyphenyl) fluorene.
- the crystalline substance (wet body) was dried under reduced pressure with 5 O: to obtain 137 g of 9, 9-bis [4- (4-aminophenol) phenyl] fluorene.
- the yield of the obtained product was 95.9% based on the dinitro compound, and the purity of the product by high performance liquid chromatography was 99.1%.
- Example 3 Through a 2 liter four-necked flask equipped with a stirrer, thermometer, DeanS ta 1 k moisture device, and reflux condenser, 9, 9 bis (4-hydroxyl 3 — Methino ref enore) Fluorene 160 g (0. 423 mol), 4-chloronitrobenzene 147 g (0. 935 mol), carbonated potassium 129 g (0. 935 mol), toluene 50 g and dimethylformamide 800 g was added. Subsequent operations were carried out in the same manner as in Example 1 to obtain 264 g of the corresponding aromatic dinitrate mouth compound. The yield of the resulting dinitrate compound was 96.6% based on 9,9-bis (4-hydroxy-3-methylphenyl) fluorene.
- a novel aromatic diamine having a fluorene nucleus can be easily obtained.
