Embodiment 1

[0028] Preparation method of diryl iodide compound I-1:

[0029]

[0030] Benzene (50.00 mmol) was dissolved in 30 ml of concentrated sulfuric acid, and the temperature was raised to 56 ° C, and sodium highly iodate (1.86 g, 8.70 mmol) was added, and the temperature was continued at a temperature of 60 ° C. Hour. After the reaction is complete, it is cooled to room temperature, and then the reaction solution is poured into the ice water mixture, and the filter residue is discarded under reduced pressure. The filtrate is extracted 5 times with ethyl acetate, discard the organic phase, and potassium bromide into the water phase (5.00 G, 35.00 mmol) Aqueous solution of 35 mL, stirred vigorously for 2 hours, precipitated solid, decompression filtration, water washed to the filtrate, and dried on a surface vessel to give a white solid compound I-1 (65% yield of 65%). 1 HNMR (400 MHz, DMSO) δ8.18 (D, J = 8.8 Hz, 4H), 7.69 (T, J = 7.9 Hz, 2H), 7.50 (T, J = 7.8 Hz, 4H).

Embodiment 2

[0032] Preparation method of diryl iodide compound I-3:

[0033]

[0034] Trifluoromethylbenzene (52.00 mmol) was dissolved in 50 ml of concentrated sulfuric acid, and the temperature was raised to 60 ° C, and sodium metatanate (1.88 g, 8.60 mmol) was added, and the temperature was 60 ° C in 2.0 hours. Continue to react 2.0 hours. After the reaction was complete, then cooled to room temperature, and then poured the reaction liquid into the ice water mixture, and the filtration was discarded under reduced pressure. The filtrate was extracted 5 times with ethyl acetate, discarded the organic phase, and potassium bromide into the water phase (7.00 G, 38.00 mmol) Aqueous solution 35ml, stirred vigorously for 3 hours, precipitated solid, decompression filtration, water washed to the filtrate, and dried on a surface vessel to give a white solid compound I-3 (64% yield of 64%). 1 HNMR (400 MHz, DMSO) δ8.45 (D, J = 9.1 Hz, 4H), 7.55 (M, 4H).

Embodiment 3

[0036] Preparation method of diryl iodide compound I-4:

[0037]

[0038] The fluorine (51.00 mmol) was dissolved in 40 ml of concentrated sulfuric acid, and the temperature was raised to 58 ° C, and the sodium metatanate (1.86 g, 8.70 mmol) was added, and the temperature was continued under conditions of 60 ° C. 1.6 hours. After the reaction was complete, then cooled to room temperature, and then poured the reaction liquid into the ice water mixture, and the filtration was discarded under reduced pressure. The filtrate was extracted 5 times with ethyl acetate, discarded the organic phase, and potassium bromide into the water phase (6.00 G, 36.00 mmol) Aqueous solution was 35mL, stirred vigorously for 2 hours, precipitated solid, decompression filtration, water washed to the filtrate, and dried on a surface vessel to give a white solid compound I-4 (68% yield of 68%). 1 H NMR (400 MHz, DMSO) Δ8.40 (D, J = 8.9 Hz, 4H), 7.45 (M, 4H).

Abstract

The invention discloses an application of a diaryl iodized salt compound in preparation of a glass antifogging agent, the structure of the diaryl iodized salt compound is shown as a general formula I, and in the general formula I, R is selected from hydrogen, C1-C5 alkyl, C1-C5 alkoxy, nitryl, halogen, fluorine-substituted C1-C5 alkyl and fluorine-substituted C1-C5 alkoxy. The diaryl iodized salt compound prepared by the invention can be used as a novel resin glass antifogging agent, and has the advantages of safety, environmental protection, high efficiency and the like when being applied to the field of resin glass antifogging agents.

Description

Technical field [0001] The present invention belongs to the preparation of the anti-fogging preparation, and in particular, the application of a diaryl iodide compound is prepared in the preparation of a glass amplifier. Background technique [0002] Anti-fogging has begun to develop in the United States early in the 1970s, and the main component of the developed anti-fogging is an acrylic resin and an organopolysiloxane, which is applied to plastic products and glass products. In the 1980s, the development of the anti-fogging agent began to rise and have a large number of papers and patents. In my country, China has been developed late in the anti-fogging agent, and more silicon is mainly, and the silicon-containing anti-fogging effect is better than the fluorine-containing anti-fog. At present, the anti-fog products in the domestic market are not much type. At present, although there are some glass and resin glass anti-fog products, there is a shortcoming, especially the anti-f...
