3,4,5,6-Tetrachlorophthalonitrile Chemical Properties,Uses,Production

Uses

3,4,5,6-Tetrachlorophthalonitrile can be used as a reagent in chemical reactions or as an intermediate in organic synthesis. 3,4,5,6-Tetrachlorophthalonitrile and 3,4,5,6-Tetrachlorophthalonitrile can be used as substrates with various phenoxy compounds in nucleophilic aromatic substitution reactions to prepare 3,4,6-trihalo-5-p-substituted phenoxyphthalonitrile containing four substituents other than hydrogen[1].

Synthesis

The quantitative o-xylene will be sent to the vaporizer for vaporization, after the o-xylene is vaporized, it will be taken out of the vaporizer by air and mixed with ammonia in the mixer and then enter into the fluidized bed, the molar ratio of three kinds of gases (vapors) is toluene vapor: ammonia: oxygen (or air) = 1:2:8, the temperature of the fluidized bed will be adjusted to 320 , the pressure will be 0.05 Mpa, and the catalyst which accounted for 0.2% of total volume of the gases in the reactor will be added as active ingredient. V2O5 as the active ingredient of the catalyst to make the reaction, the gas after the reaction is cooled down and sent to the collector, the product phthalonitrile is obtained after condensation and drying, the yield of the product is 80%-90%, and the purity is 99%; phthalonitrile is sent to the vaporizer for melting and vaporization, and the phthalonitrile is vaporized by nitrogen out of the vaporizer and mixed with the chlorine in the mixer. Into the fluidized bed, the molar ratio of the inlet gas is phthalonitrile vapor: chlorine: nitrogen = 2:5:10, while adding catalyst activated carbon, the amount of total volume of 0.2% of the bed, the temperature of the fluidized bed is adjusted to 230 C, the pressure is 0.01MPa-0. After the reaction is completed, the reacted gas will be sent to a fixed bed to maintain the same temperature and pressure as in the fluidized bed, and add and add the fluidized bed to a fixed bed to maintain the same temperature and pressure. After the reaction was completed, the post-reaction gas was fed into the fixed bed, maintaining the same temperature and pressure as that of the fluidized bed, and the same amount of catalyst activated carbon and chlorine was added as that of the fluidized bed, so as to make the post-reaction gas and the chlorine react again, and the post-reaction gas mixture in the fixed bed was fed into the receiver, and the 3,4,5,6-tetrachlorobenzene-1,2-dicarbonitrile was obtained by condensation and drying. The yield of the reaction was 85%-95% and the purity of the product was 98%.
