| Application | hexaaryl biimidazoles are a class of organic compounds (abbreviated as ABI), typically hexaphenyl biimidazoles. 2,2 '-bis (2-chlorophenyl)-4,4'5,5'-tetraphenyl-1, 2 '-bis-imidazole is The photoinitiator O-chlorohexaaryl bis-imidazole (BCIM), the existing synthesis method is to use sodium hypochlorite as the oxidation condensation agent for the synthesis of BCIM, which brings more alkaline "wastewater" with low yield and high cost. |
| preparation | A preparation method of diimidazole photoinitiator, the specific steps are as follows:(1) add 30% ml of water or the previous batch of reaction mother liquor and 50g of 1 ml liquid alkali into a 100 ml glass reaction flask, stir and mix well;(2) add g of BCIM-monomer wet material, stir for 15 minutes, then add 300g of dichloromethane and 6g of dodecyldimethyl benzyl ammonium chloride;(3) Keep the temperature at 20-35 ° C., slowly drop 50g of 30% hydrogen peroxide for 4-6 hours, add it and stir for 60 minutes;(4) sample for liquid chromatography analysis; If the weight percentage of unreacted BCIM-monomer wet material is more than 0.5%, add 30% hydrogen peroxide, the weight is 2 times the weight of the unreacted BCIM-monomer wet material analyzed by liquid chromatography;(5) stirring for 1 hour, repeating the 4th step, until the unreacted BCIM-monomer wet material content is less than 0.5% by weight; (6) the reaction solution is poured into a 1000ml separatory funnel, and allowed to stand for 15 minutes to clarify, and then the aqueous layer is separated;(7) 200ml of water is added to the dichloromethane layer, and after stirring for 5 minutes, (8) separate the washed water layer, add deionized water, stir for 30 minutes, and then stand for 1 hour;(9) Pour the organic layer into a 500ml distillation flask, dichloromethane can be recovered by heating under normal pressure, and the dichloromethane recovered by distillation can be used for the next batch of reaction;(10) add 200ml isopropanol, continue distillation, and stop distillation when the reaction solution becomes turbid;(11) under stirring, add cold water, cool to room temperature, and filter; (12) the filter cake was slightly washed twice with fresh isopropanol;(13) dried in a drying cabinet to give 93-95g of yellow BCIM crystals in 93%-95% yield. |
