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. 355-43-1, name is 1,1,1,2,2,3,3,4,4,5,5,6,6-Tridecafluoro-6-iodohexane, A new synthetic method of this compound is introduced below., Formula: C6F13I
In reaction kettleF (CF2) 6-I(1298.5 kg, 2.911 kmol)Was stirred and stirred.Next, Parroyl IPP[Half-life temperature: 40.3 C]AE-3000 so that 20% by massSolution dissolved in (1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether)(17.0 kg, 0.017 kmol)And CH2 = CHCH2 (CH2) 5H (336.5 kg, 2.999 kmol)It was dripped at the said reaction kettle.During dripping,The internal temperature was kept at 88-100 C.After completion of drippingKeep the internal temperature at 90-100 C,As a result of analyzing the reaction crude liquid A1 obtained by further stirring for 0.5 hour or more by gas chromatography,It was confirmed that F (CF2) 6CH2CHICH2 (CH2) 5H was contained.From the obtained reaction crude liquid A1,Under reduced pressure (-0.093 kPaG.Less than,Gauge pressure,?G? is added after ?kPa? or ?MPa?. )AE-3000 and excessCH2 = CHCH2 (CH2) 5HIs distilled off,Reaction solution 1a containing F (CF2) 6CH2CHICH2 (CH2) 5H(1622.4 kg) was 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.
