Above-mentioned organic solvent can be following one of in all kinds of or the mixture of arbitrary proportion: 1. carbonatoms is 1～4 halohydrocarbon; 2. carbonatoms is 1～7 ester class; 3. carbonatoms is 3～6 ketone; 4. carbonatoms is 2～6 ethers; 5. Nitromethane 99Min.; 6. oil of mirbane.As can being one of following or its mixture: methylene dichloride; Trichloromethane; Tetracol phenixin; 1, the 1-ethylene dichloride; 1, the 2-ethylene dichloride; 1; Vinyl trichloride; Methyl acetate; Ethyl acetate; Propyl acetate; Butylacetate; Isopropyl acetate; Isobutyl acetate; Pentyl acetate; Isoamyl Acetate FCC; Methyl propionate; Ethyl propionate; Propyl propionate; Butyl propionate; Amyl propionate; Acetone; Butanone; Pimelinketone etc.; Ether; Propyl ether; Isopropyl ether; Butyl ether; Nitromethane 99Min.; Oil of mirbane.One of above-mentioned organic solvent is more preferably following or its mixture: 1. methylene dichloride 2. 1, and the 2-ethylene dichloride is 4. 5. oil of mirbane of ethyl acetate of tetracol phenixin 3..
When the aromatic compound described in the present invention was liquid, described organic solvent can be an aromatic compound itself.At this moment, the molar ratio of described aromatic compound, BTC, Ytterbiumtriflate is 5～100: 1: 0.05～1.0, and being preferably is 5～50: 1: 0.05～0.2.
The recyclable utilization of catalyzer that the present invention is used, recovery method are reaction to be finished the gained filtrate decompression concentrate, washing, and thermal dehydration under vacuum promptly gets white Ytterbiumtriflate crystal, and the rate of recovery can reach 95%.That is to say that the catalyzer Ytterbiumtriflate can be concentrated by the reaction product filtrate filtered, washing, thermal dehydration makes under vacuum.
The chemical synthesis process of symmetrical two aromatic base ketone compounds of the present invention, specifically can carry out as follows:
A. be 1～10 with molar ratio: 1: 0.02～0.2 aromatic compound, BTC, Ytterbiumtriflate join in the methylene dichloride that consumption is 5～50 times of BTC quality and dissolve;
B. be warmed up to 50～80 ℃ of temperature of reaction, reacted 5～12 hours;
C. boil off solvent, the cooling, with frozen water to reaction solution to remove remaining BTC, filter to such an extent that filter cake is a product.
When above-mentioned aromatic compound was liquid state, described synthetic method also can be carried out as follows:
