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.

1163-19-5, The chemical industry reduces the impact on the environment during synthesis 1163-19-5, name is 6,6′-Oxybis(1,2,3,4,5-pentabromobenzene), I believe this compound will play a more active role in future production and life.

setupBDE209 stock solution (1 ¡Á 10-3mol/L) in tetrahydrofuran wasdiluted with methanol to 1 ¡Á 10-5mol/L. 0.05 mL pyruvic acidaqueous solution (1 ¡Á 10-2mol/L) was added to 10 mL BDE209methanol solution in a Pyrex vessel. Reaction solutions were mag-netically stirred during the irradiation. The Pyrex vessel was purgedwith argon for 30 min to remove O2and protected under argonatmosphere during the irradiation. A PLS-SXE300 Xe lamp (BeijingTrusttech Co. Ltd.) was used as the light source. To eliminate thedirect photolysis of BDE209, a cutoff filter was used to cut the irra-diation below 360 nm. To investigate the effect of acids/bases andH2O on the reaction kinetics, a given amount acid/base and H2Owere added under otherwise identical conditions. At given timeintervals, 1 mL aliquots were used for analysis.
