Electric Literature of 375-80-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 375-80-4, name is 1,6-Diiodoperfluorohexane belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
55.4 g (0.10 mol) of IC 6 F 12 I obtained in Reference Example 1 and 0.58 g (0.004 mol) of tert-butyl peroxide were added to a reactor having a capacity of 150 ml equipped with a stirrer and a thermometer. Next, VDF was added under reduced pressure until reaching 0.5 MPa, and then heating was carried out at 125 C. for 3 hours. Further, after cooling the reaction solution to 70 C., VDF was added to 0.5 MPa and heated at 125 C. for 3 hours. Further, after cooling the reaction solution to 70 C., VDF was added until it reached 0.5 MPa and heated at 125 C. for 5 hours. A total amount of 12.2 g (0.19 mol) of VDF was fed to the reactor.After cooling and discharge of the residual gas, 300 g of chloroform and 20.2 g (0.20 mol) of triethylamine were added to this product, and the reaction was carried out at 35 C. for 3 hours. 150 g of water and 25 g of a 10% hydrochloric acid aqueous solution were added to the obtained reaction solution, and the liquid separation operation was carried out to obtain an organic layer.Chloroform was distilled off from the organic layer, then distilled,17.8 g (yield 42%) of a 6E-T 2 T fraction (purity 99%) having a boiling point of 76 C. (13.33 kPa) of the following formula (12)3.6 g (yield 7%) of a 6E-1 T fraction (purity 97%) having a boiling point of 63 C. (4.00 kPa) of the following formula (13)9.8 g (yield 20%) of a 6E-T 3 TT fraction (purity 97%) having a boiling point of 74 C. (4.00 kPa) of the following formula (14) and 6 E- 0.8 g (yield 1%) of 2TT fraction (purity 98%) was obtained.The structure of the obtained fraction was confirmed by 1 H-NMR and 19 F-NMR.
The synthetic route of 1,6-Diiodoperfluorohexane has been constantly updated, and we look forward to future research findings.
