These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Diphenyl oxide, its application will become more common.
Reference of 101-84-8,Some common heterocyclic compound, 101-84-8, name is Diphenyl oxide, molecular formula is C12H10O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
The reactor was charged with 3.16 g of AlCl3 and 711 g of bromine. Diphenyl oxide (46.1 g, 0.271 mol) and the Br2/Cl2 mixture (BrCl) were cofed to the reactor during 124 minutes at 55 C to 57 C. The rate of addition was at a proportion of about 8.2 g Br2/Cl2 mixture (BrCl) per gram of DPO, such that the addition of both was completed at the same time. The mixture in the reactor was refluxed for 10 minutes after the cofeeds had ended, and deionized H2O was added. The reactor was set for distillation. The halogen (mostly Br2, but also comprised of BrCl and Cl2) was distilled off. When most of the halogen was gone, more deionized water was added. The remaining halogen was distilled off to 1000C. The remaining mixture was cooled to 6O0C, and 30 mL of 25% NaOH was added to pH 13-14. The resultant mixture was filtered and washed well with deionized water. A sample was subjected to GC analysis. The GC trace showed the product to contain 0.26% Br9DPO (meta and para hydrogen isomers only), 2.52% Br9ClDPO, and 97.2% Br10DPO. None (less than 0.02%) of the ortho hydrogen isomer of Br9DPO was detected. The sample was oven dried. [0043] The drawings show illustrative GC traces formed using the recommended gas chromatographic procedure described hereinabove. In these traces, the abscissa is time in minutes and the ordinate is the detector response. A copy of the GC trace of the product formed in Example 1 appears as Fig. 1. In Fig. 1, the peak at 1.358 represents the area percentage of what is deemed to be the meta and para isomers of nonabromodiphenyl oxide. No peak for the ortho-isomer of nonabromodiphenyl oxide was observed. The peaks at 2.103 and 2.200 were deemed to be Br9ClDPO isomers. The peak at 2.649 represents the area percentage of decabromodiphenyl oxide.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Diphenyl oxide, its application will become more common.
