Related Products of 1163-19-5, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1163-19-5 as follows.
Using CdSe quantum dots as photocatalyst, take 10 mL of quantum dot stock solution, add appropriate amount of hydrochloric acid, centrifuge, discard the supernatant to retain solids, and redistribute the quantum dot solids to 4 mL of N,N-dimethylformamide (DMF). The concentration of the quantum dots was 2.47¡Á10-5 M; decabromodiphenyl ether (0.05 mmol) and triethylamine (2.5 mmol) were added to DMF, the rubber stopper was sealed, and the atmosphere was degassed for 20 min to remove the system. The oxygen in the room was irradiated for 24 hours at room temperature with an LED lamp (lambda > 460 nm). After the reaction, the yield and selectivity of diphenyl ether were determined by GC (FID) using diphenylacetonitrile as an internal standard. The debromination efficiency of decabromodiphenyl ether was determined by ion chromatography using sodium chloride as an internal standard. The experimental results show that decabromodiphenyl ether can be completely removed by quantum dot photocatalytic reduction and dehalogenation hydrogenation. The debromination efficiency is 65%, the yield of diphenyl ether is 54%, and the selectivity is as high as 83%.
According to the analysis of related databases, 1163-19-5, the application of this compound in the production field has become more and more popular.
