production method

1. make four (triphenylene) put LI) in a 2-liter round-bottom flask with less depressurization after a permanent bubble meter (one outlet pipe is sleeved with a rubber cap, and the other is connected with a nitrogen vacuum system, place 17.72 grams (0.10 moles) of dichloride, 131 grams? (0.50 moles) triphenylphosphorus and 1200 ml of dimethylanthus, stir and heat in an oil bath (about 140) to dissolve the yellow mixture formed. Sprinkle the oil bath, quickly stir for about 15 minutes, quickly inject 20 grams (0.40 moles) of hydronium with a syringe (within 1 minute), and then a fierce reaction occurs to release nitrogen. Immediately cool the formed dark solution with a water bath and let it begin to crystallize at about 125 ℃. Sprinkle the water bath and let it cool to room temperature by itself. Filter with a coarse sand core funnel in the presence of nitrogen, and wash with 50 ml of ethanol and 50 ml of ether twice in turn. From the funnel through a slow nitrogen stream overnight to dry the product, 103.5 grams (90-94%) of yellow crystals were obtained. 2. The preparation of the chlorinated bis (triphenylene) chlorination at room temperature and under stirring, the chlorine is added to the suspension of the tetrakis (triphenylene) mixture and benzene to obtain a product with a yield of pocket%. Mutual crystallization in chloromethane monohexane.
