Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2043-55-2, name is 1,1,1,2,2,3,3,4,4-Nonafluoro-6-iodohexane, A new synthetic method of this compound is introduced below., name: 1,1,1,2,2,3,3,4,4-Nonafluoro-6-iodohexane
(2) In another 4 liters of the pressure-resistant reactor, 750 g of perfluorobutylethyl iodide obtained in (1) was added, and the mixture was heated to 125 ¡ã C with stirring. A 3000 g solution of 5percent aqueous dimethylformamide was added to the reactor at a rate of 30 g/min using a metering pump. The temperature was controlled at 125-130 ¡ã C, the pressure was not higher than 1.2 MPa, and the reaction was continued for 30 hours.Remove the heat.The organic phase was separated by neutralizing with 1000 g of a 11.3percent aqueous potassium hydroxide solution.Wash once with 1000 g of deionized water, separate the organic phase, remove the light components,490 g of an intermediate product of 85percent of a fluorine-containing alcohol and 8percent of a fluorine-containing olefin were obtained.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
